Barstool Sports‘ Dave Portnoy lamenta ter faltado ao ganhar 5 milhões de dólares de Bitcoin

Sempre com tanta freqüência, o preço do Bitcoin faz um aumento louvável, e os céticos recuam em sua tomada anterior em baixa. Aconteceu com a cantora Lily Allen, que teria sido mais rica do que a rainha da Inglaterra, se ela tivesse dito sim a uma apresentação virtual de Bitcoin que se ofereceu para pagar suas 200.000 Bitcoins.

Depois que ele comprou $1 milhão de dólares de Bitcoin

US$12,56 bilhões poderiam ter sido adicionados ao patrimônio líquido da cantora, se ela tivesse aceitado o show. Em agosto do ano passado, a comunidade Bitcoin Era comemorou a chegada de Dave Portnoy, o fundador da Barstool Sports, depois que ele comprou $1 milhão de dólares de Bitcoin.

Foi como de costume um grande negócio, e a Crypto-Twitter, como de costume, inundou a linha do tempo com tweets de felicitações, na esperança de que investidores mais tradicionais se inspirassem a arriscar na Bitcoin.

Mas Portnoy recuaria em sua decisão quando os preços caíram e o levou a perder 25.000 dólares depois que ele vendeu. Mas, assim como muitos abreviadores de Bitcoin, a história muitas vezes termina em insatisfação. Isto foi provado objetivamente por muitos Bitcoiners que inicialmente abandonaram o ativo em seus primeiros dias.

Agora Portnoy foi levado ao Twitter para expressar desapontamento por sua decisão de trocar a Bitcoin por suas propriedades. Em um vídeo ele legenda „Emergency Press Conference, I Fucked Up Bitcoin“, o CEO pode ser visto expressando sua frustração com a venda da Bitcoin que lhe teria rendido quase US$ 5 milhões, se ele tivesse mantido o ativo por um pouco mais de tempo.

Os evangelistas de Bitcoin foram rápidos

A partir de seu vídeo no Twitter, ele pode ser ouvido dizendo:

„Eu quero parabenizar todo o meu pessoal Bitcoin lá fora. Quando você está errado, você está errado, eu o vendi com a porra do papel. Eu não posso aceitar Bitcoin, os altos e baixos, eu gostaria de tê-lo. Peguei todo o meu dinheiro e coloquei o que eu acho que sei, o que posso controlar. Eu fodi tudo“.

Enquanto ele ainda não revelou se conseguiu mais Bitcoin recentemente, é possível que isso já tenha acontecido. Os evangelistas de Bitcoin foram rápidos em incentivar Portnoy, enfatizando como ele ainda está no mercado, o que grandes jogadores como CZ ainda consideram estar em sua fase inicial.

Na verdade, se Bitcoin continuar a dançar no tom de alta geralmente previsto, Portnoy poderá fazer muito mais no futuro do que havia perdido anteriormente. Embora como ele observou em seu vídeo, que seu conhecimento da dinâmica do ativo pode não ser tão suficiente, isto contrasta com o que os analistas propuseram como mais lucrativo para os novatos de Bitcoin: HODLing.

Start-up DIEM threatens Facebook with legal action

A London FinTech start-up wants to stand up to the planned Facebook Coin Diem (formerly: Libra): It claims the name DIEM for itself.

But the decision to rename Libra to Diem was apparently made over a year ago

The fact that Facebook has to take into account many legal pitfalls with its planned cryptocurrency is made clear by the increasingly louder concerns of finance ministers, central banks and regulatory authorities . Now the Facebook Coin, which has long operated under the name Libra, could also face trademark consequences. The reason lies in the recently adopted rebranding where Libra in „Diem“ rechristened was. The problem: the name is already taken.

JustTRADE is the first German provider to offer an all-in-one solution for trading cryptocurrencies (Bitcoin, Ethereum, Ripple, …) stocks, ETFs and Bitcoin Evolution. The website and app are designed to be intuitive, offer many useful features and are suitable for both beginners and advanced traders. The best: there are no transaction costs or network fees.

Find out more now

A FinTech start-up from London claims the name. This is reported by the FinTech news portal Sifted. There, Geri Cupi, co-founder and CEO of the start-up founded in 2020, is indignant:

We were amazed on December 1st to find out that Facebook’s Libra Foundation had decided to rename their brand to Diem … As a small start-up, we are concerned that customer confusion resulting from Libra’s actions will significantly affect our growth. […],

lamentiertthe 27-year-old Albanian, who, as co-founder of the blockchain start-up MonoChain, has a place in the Forbes list 30 Under 30 (category Europe, retail / e-commerce).

The start-up describes itself as the „Bank of Things“ and is still in the early stages according to the corporate data portal Crunchbase. At the end of September, DIEM received an undisclosed amount of pre-seed funding from angel investor Chris Adelsbach. According to Sifted, there was a soft launch at the beginning of October.

Now DIEM is apparently worried that Facebook will take the name for itself and its stablecoin project. It would only have taken a short research to find out that there is already a financial service provider (in particular) with the name Diem, says financier Adelsbach:

It wouldn’t have taken that much effort for Facebook to figure out if there was another Diem in the financial services industry … They apparently thought „we’re just going to crush them, we’re Facebook“

Bitcoin price hits USD 19,000 and bullish players are confident about a record gap in BTC futures

Despite the 15% gains produced over the weekend, Monday offers more of the same for Bitcoin than before the opening of Wall Street.

The price of Bitcoin (BTC) returned to $19,000 on November 30, as a weekend surge continued to produce further gains for investors and traders.

How to use modern portfolio theory in Bitcoin?

Diversification can be our ally in the middle of this field of volatility.

Modern portfolio theory (MPT) has long been one of the most accepted financial portfolio optimization theories in the world of large investments. More than a theory, it is a practice that is widely used by portfolio managers. Basically, it’s a model that combines different types of assets, taking into account their profitability and risk, calculating past volatility and market correlation. Does it apply to Bitcoin Profit platform investments?

This theory is born from academia and is a theory derived from the theory of the efficient market. In fact, its creator and main exponent, Harry Markwitz, Nobel Prize in Economics in 1990, built his theory on the efficient market theory. In other words, the two theories are closely related. Since its creation in 1952, modern portfolio theory has enjoyed great popularity in the investment world. And one could say that it is considered the norm. Its popularity is due in part to its great simplicity.

Why isn’t the scarcity of Bitcoin the key?

Of course, despite its success, this theory has many critics. In fact, it’s considered absurd by many reputable investors. By Warren Buffett and Charlie Munger, for example. Well, in general terms, it is criticized by all the critics of efficient market theory. This includes primarily value investors and opposites. In other words, all those who think that markets are essentially irrational.

Now, if we go straight to the results, modern portfolio theory is quite mediocre. In this sense, value investing, as an investment strategy, has yielded better results. In this case, Buffett and the other disciples of Ben Graham have a basis for dismantling modern portfolio theory.

What is the underlying problem? One of the problems is the use of volatility as a primary measure of risk. That is, it reduces risk to a simple number. Of course, in practice, many of us fall into the trap of saying that volatility is risk for simplicity’s sake. However, it is not that simple. It is obvious that the risk of a business goes much further. Logically, there are other factors that we must take into account, such as its indebtedness, the valuation of its assets, its business model, sales, and its market share. In short, if a business produces profits constantly, the risk decreases. It doesn’t matter much about the volatility of its actions.

Here’s something to think about when it comes to diversification. If you have a good business, it would not make sense to diversify. In other words, having several mediocre businesses instead of one good one does not reduce risk. In this case, diversifying would be absurd.

Modern portfolio theory places too much importance on past data. That is, it is based on the premise that with past performance and volatility data, future performance and volatility can be calculated. And thus ignoring other variables. This emphasis on quantitative factors for the composition of a portfolio underestimates the irrationality of the markets and the surprise factor.

How to build a good portfolio of investment in cryptosystems?

However, one could conclude that volatility is not the only element to determine the risk of a business or other productive asset. However, in the case of a merely speculative asset, the volatility factor does take on greater importance. The mere fact that it has no use value or intrinsic value, only exchange value, places a greater weight on variations in the exchange rate.

Let’s suppose for a moment that we borrow in dollars. If our income is in dollars, we will most likely be able to sleep soundly, because the dollar is an extremely stable currency. In this sense, the risk is relatively low. The matter changes if the loan is in dollars, but our income is in Venezuelan bolivars or Argentinean pesos, for example. In this case, it would not be unreasonable to say that the volatility of the local currency increases the risk of the operation.

Now let’s suppose that we apply for a bank loan to invest in Bitcoin. If we listen to the crypto-influencers in vogue on Twitter, this operation would not be very risky. After all, according to the official story, Bitcoin is a „safe haven“ and fiat money will soon collapse. Apparently, the scarcity of Bitcoin guarantees its value in all climates. However, this supposed Bitcoin security is just rhetoric. Because no one in their right mind would think that the idea of this reckless loan would be risk-free. The green

Virgil Griffith lucha contra Corea del Norte

Virgil Griffith lucha contra Corea del Norte ayudando a presentar cargos contra los EE.UU.

El desarrollador de Ethereum y creador de Wikiscanner, Virgil Griffith, presentó una moción la semana pasada para desestimar las acusaciones del gobierno de EE.UU. de „ayudar“ al gobierno de Corea del Norte, según los documentos publicados la semana pasada.

Griffith fue arrestado en noviembre del año pasado después de hablar en una conferencia sobre la criptografía norcoreana. Las autoridades alegaron que violó la „Ley de poderes económicos en caso de emergencia internacional“ al visitar el país restringido y además alegaron que Griffith había demostrado el uso de la tecnología de cadenas de bloqueo para eludir las sanciones económicas.
El desarrollo del etéreo lucha contra las acusaciones de los Estados Unidos

El abogado Brian Klein, que representa a Griffith, declaró que las autoridades de EE.UU. no „especifican ningún supuesto hecho manifiesto“ y no contienen ninguna „alegación de hecho“ real. La moción considera además que el intercambio 1k Daily Profit de información (como lo hizo Griffith en Corea del Norte) es un acto legal, que no desafía las sanciones de los Estados Unidos.

„Parece que la teoría del gobierno es que, al asistir y hablar en una conferencia sobre cadenas de bloqueo en Pyongyang, el Sr. Griffith prestó ’servicios‘ porque ‚proporcionó a la República Popular Democrática de Corea información valiosa sobre tecnologías de cadenas de bloqueo y de criptografía, y participó en debates sobre el uso de tecnologías de criptografía para eludir las sanciones y blanquear dinero“, se lee en la moción.

Pero los defensores no están de acuerdo. Klein afirma que Griffith habló sobre asuntos y enumeró información que ya es de dominio público – nada que sea propiedad o esté protegido por la ley en los Estados Unidos.

Se lee:

„Sabiendo muy bien que el Sr. Griffith como mucho asistió a una conferencia por su cuenta, y dio un discurso muy general basado en información disponible al público – como lo hace casi mensualmente en conferencias en todo el mundo – el gobierno ha decidido, sin embargo, acusarlo de proporcionar „servicios“ a la República Popular Democrática de Corea („RPDC“)“.

La primera sanción de este tipo

En la moción se señalaba además que el Presidente de los Estados Unidos no tiene autoridad para controlar la transmisión de información pública y que no existen „directrices para aclarar la definición de servicios“ emitidas por órdenes ejecutivas o por la Oficina de Control de Activos Extranjeros (OFAC).

„Este es un defecto material porque el delito imputado está en una zona donde el panorama legal está lejos de estar resuelto y se necesitan más detalles“.

La moción concluía con los puntos anteriores, „Debido a todos estos defectos graves y fatales, el Sr. Griffith pide respetuosamente a este Tribunal que desestime la acusación con perjuicio“.

La sanción es la primera instancia de un caso legal que involucra „servicios“ de criptografía prestados a un país restringido como Corea del Norte; la conclusión a la que puede sentar el precedente de cómo se abordarán legalmente estos casos en el futuro.

Trader paid in Bitcoin to be released from kidnapping

The crime has shocked authorities in two countries and has an international investigation to determine the fate of the money.

A trader has been kidnapped in the last few days and his family has been threatened with international connections. To be released, the trader paid in Bitcoin to be released from captivity where he was held.

The situation was tense during the kidnapping, which lasted at least five days. Police investigations are still being conducted into the crime and several authorities are participating.

The case, which took place in Argentina, shows how common the adoption of Bitcoin is in the country. In order to be released, the criminals asked the family members for the sum of $35,000.

The merchant had been kidnapped on October 13.

Trader paid in Bitcoin to be released from kidnapping

A serious case of extortion and kidnapping has occurred in Argentina in recent days. The country’s authorities are still investigating the case, including the Argentine Federal Police.

A 46-year-old merchant left his home and was on his way to his shop on the 13th. Halfway there, he was approached by a gang of kidnappers, who approached his car, a Ford EcoSport.

The shopkeeper owns the „Don Santiago“ supermarket in the city of Quilmes, near Buenos Aires. Upon arriving with the kidnappers in captivity, the man began to see his family blackmailed to pay the ransom.

He drew the authorities‘ attention to the fact that the calls came from international numbers. They were numbers from Venezuela and Colombia, a fact that frightened the relatives of the trader. In addition to calls, text messages and WhatsApp were sent by the kidnapped to the victim’s brother.

In principle, the kidnappers were asking for the sum of $650,000 to release the trader, who was not named. The amount, with the price of the dollar today, would give the equivalent of R$ 3635 million.

With the denunciation by the police authorities, the case ended up in the Federal Police and Departmental Delegations of Investigations (DDI) of Argentina and also in the National Police of Colombia.

After days of negotiation, it was agreed that the family would pay 4 Bitcoins for the ransom of the trader. The amount would be the equivalent of U$ 35 thousand, or R$ 195 thousand today.

Even after the „discount“, the kidnappers still wanted more money

According to the Argentinean portal Telam, despite the discount on the initial order, there was pressure for more money. Despite this, the kidnappers ended up giving in after seeing that there would be no more money and released the man in front of his market on the last 18th.

The kidnapping that lasted five days is a more emblematic case involving Bitcoin in Argentina now. The investigations, which arrested the wife of one of the participants, indicate that the gang consists of three people.

According to information obtained by Telam, the police are looking to trace Bitcoin to find out where he will end up. In this way, help has been requested from other countries and there is international cooperation to unravel the mystery.

It is worth mentioning that in Argentina today it is increasingly common for the population to use Bitcoin. Digital currency is one of the means that the population uses as a store of value, because the Argentine peso is losing more and more of its purchasing power.

Finally, in other kidnappings that requested Bitcoin in Argentina, there was no payment for the ransom. However, this is the first case already registered in the country of a kidnapping that effectively paid the ransom in digital currency.

In Brazil, the police recently dismantled a kidnapping that requested Bitcoin for the ransom of a woman. After 12 hours in captivity, the woman was finally released by the police and the prisoner of the crime.
