Nouriel Roubini
New York University professor Nouriel Roubini is a prime representative of those who do not like the crypto industry.
He made quite a few bright and provocative statements about BTC and not only. One of his most famous statements, published on Twitter five years ago:
“Decentralization of cryptocurrency is a myth.. This system is more centralized than lade North Korea: miners are centralized, exchanges are centralized, developers are centralized dictators.
Buterin is a dictator for life, and BTC’s Gini coefficient is worse than North Korea’s.
In 2023, Roubini again loudly expressed his stance on cryptocurrencies. According to the scientist, the industry is criminal, and 99% of all projects are either “fraudulent schemes” or pyramids.
In addition, all those involved in the creation of cryptocurrencies should sit in prison, and investors should not invest in such assets.
In March 2023, Roubini spoke in support of SEC head Gary Gensler’s position that ether is a security.
Peter Schiff
The owner of management company Euro Pacific Management Peter Schiff has repeatedly stated his dislike for the world’s first largest cryptocurrency by capitalization.
He compared bitcoin to a ship in distress, and in December 2022 he predicted a price of $5,000 (then it was only $15,000) and even called a potential fall to zero a reality.
For now, however, all these attacks against BTC, for the most part, remain noise, and bitcoin in the afternoon of Monday, May 29, is worth about $26 & nbsp;700.
Commentators on social media find Schiff’s position biased and hypocritical.
First, he himself talked about the fact that he had a Bitcoin wallet in the past, but access was lost because the businessman didn’t write down the SID phrase.
Then Schiff openly regretted that he didn’t buy BTC in 2011. And recently the expert announced about creation of an NFT collection based on Bitcoin. 
Warren Buffett
Warren Buffett is one of the world’s best-known investors, the proud owner of the nickname “The Oracle of Omaha.
He has always shown his aversion to cryptocurrencies. Investor compared them to the lottery and even to gambling.
Buffett is a proponent of investing in the real economy.
At the annual meeting of his investment company Berkshire Hathaway in 2022 the investor said that he would not buy all the bitcoins for $25, because once he owned all the BTC, he would not know where to put them, and no one would want the bitcoins.
At the same time, if he were offered to invest in 1% of all apartment buildings in the U.S. or 1% of farmland, he would not hesitate to give $25 billion.
The investor explains his position by saying that it is possible to live in the houses and grow food on the land.. With bitcoins, on the other hand, according to Warren Buffett, there’s nothing to do.
In 2018, the investor made even stronger statements about the first cryptocurrency. For example, called bitcoin “rat poison squared.
For all that the “Oracle of Omaha” is no crypto-enthusiast, in early 2022 Berkshire Hathaway invested about $1 billion in cryptocurrency-friendly Nubank. 
Charles Munger
Charles Munger is vice chairman of Berkshire Hathaway, U.S.. He said back in 2018 that bitcoin is, in a sense, “worthless artificial gold.”. The executive told CNBC:
“The fact that computer science is smart does not mean that cryptocurrency should be used everywhere, and that respectable people should convince others to speculate on such.
Bitcoin reminds me of Oscar Wilde’s definition of fox hunting: “The pursuit of that which cannot be eaten by those who cannot speak.”
In 2022, a Warren Buffett associate compared bitcoin to an “STD.”
In his opinion, it’s an asset invented “out of nothing” that has attracted a lot of money. Munger himself has never invested in digital currencies.
In 2023, the famous investor found another comparison for cryptocurrencies.
From his point of view, cryptoassets have become gambling, compared to which the casino has almost a hundred percent advantage.
Charles Munger called for a ban on cryptocurrencies in the U.S. and praised Chinese leader Xi Jinping for banning cryptocurrencies in the Middle Kingdom.
Bill Gates
Microsoft founder Bill Gates doesn’t see the point in crypto investments because they, in his opinion, are not useful.
He also doesn’t like non-fungible tokens (NFTs) because they are based on the “big fool” theory.
Gates, in an interview with CNBC’s Andrew Ross Sorkin in 2021 spoke about bitcoin’s negative impact on climate change.
According to the businessman, Bitcoin uses more electricity per transaction than any other method known to man, and it’s not a brilliant thing for the climate.”
It’s worth noting that the negativity toward cryptocurrencies from Bill Gates has only appeared in recent years.
Back in 2014, the creator of Windows was not so categorical. On Bloomberg, he said:
“Bitcoin is better than currency because you don’t have to be physically in one place, and of course, for large transactions, currency (fiat) can be quite inconvenient.”
Benjamin McKenzie
Actor Benjamin McKenzie, known for his roles in the TV series “Lonely Hearts” and “Gotham,” is interested in cryptocurrency recently – in 2021.
He took the Gary Gensler course and came to the disappointing conclusion that “the crypto market is designed for fraud.
In actor’s opinion, the rapid change in the prices of cryptocurrencies is speculative in nature and they have no practical application:
“Cryptocurrencies don’t do what conventional currencies do. They are not a store of value, a unit of account, or a measure of exchange.
In an interview with The Wall Street Journal, McKenzie said that from his perspective, cryptocurrency emerged as people needed.
Nevertheless, its true value is completely different from the stated. The actor believes that any digital currency is absolutely centralized.
He compares cryptocurrencies to playing poker against what he considers to be the best player, Phil Helmuth.
If you do well, as in the cards, there is a chance to win, but in most cases you are doomed. The actor believes that the activities of famous people who support the crypto industry are immoral;
Elizabeth Warren
Elizabeth Warren is a Democratic U.S. senator and fierce cryptoskeptic. One of her attacks on the industry was a comparison of cryptospace with the bubble of 2008.
In her opinion, history is repeating itself, as experts said then and now that all was well. Both stories, however, must have a sad ending.
Warren uses each new industry collapse to launch new attacks on cryptocurrencies.
In the summer of 2022, after the problems that happened with Celsius, Voyager and others, the senator called for stricter industry controls to protect crypto investors.
In March 2023, Warren called for a so-called “anti-crypto army.”. Otherwise, investors
will continue to lose their investments in the so-called “new wild west.”
Warren isn’t just paying lip service to trying to limit the crypto industry’s activities. She’s trying to push through her version of the money laundering law.
The current one, in her opinion, is not good enough.
Jim Cramer
Jim Cramer is the host of MadMoneyGram on CNBC. He constantly declares that he would sell all his bitcoins if he had them, or that he wouldn’t invest in cryptocurrencies at all even in a million years.
In 2021, Kramer himself said he sold off some of his bitcoins to pay his mortgage. Moreover,
admitted:
“Now I have a house and stocks and barrels because I bought that currency.”
This “cryptoskeptic” himself admitted in the summer of 2022 that he has ether on his hands.
This allows the broadcaster to make money, which is impossible, according to Kramer, on investments in the NFT. He bought them with ethers, too.
And then said, “I had to buy NFTs on Etherium, I studied them: collectible tokens have several qualities that I like.”
Jamie Dimon
JP Morgan Bank CEO Jamie Dimon thinks bitcoin is a “hype scam.”
However, he has a completely different attitude towards blockchain technology because it is just a convenient solution for transmitting information.
Dimon does not deny the possibility of bitcoin rising to huge values before it collapses:
“I’m not telling you to short …. Bitcoin can get to $100 000 before it goes down – but that’s not advice on what to do.”
Overall, the JP Morgan CEO is fairly consistent. In an interview with Bloomberg in 2021, the banker stated:
“I personally don’t think bitcoin has any value. But I don’t care about that. To me, there’s no difference. Our customers are adults.
They don’t agree. That’s what markets do. If they want to buy or sell bitcoins, it’s hard not to give them access. But we can give them the legitimate, cleanest possible solution.”
Ray Dalio
Ray Dalio is the founder of the investment firm Bridgewater Associates. The businessman prefers gold to cryptocurrency.
True, he has a certain amount of bitcoins.. Dalio believes that BTC is “just a younger alternative to gold.
At the same time, According to the businessman, bitcoin has no intrinsic value, only imputed value, which is an advantage.
Back in 2021 Dalio admitted that he has not only BTC, but also ether,
explaining it this way:
“I can see how alternative money operates in an environment where the value of cash has diminished.
And I find it very impressive that over the last 10-11 years this program has held up and it hasn’t been hacked. I’m a big fan of diversification.”
The financier Believes: “Digital currencies are not like anything, they can rise or fall. But cryptocurrencies are definitely not a hedge against inflation or an effective store of value;
Conclusion: why cryptoskeptics are needed
In short, most cryptoskeptics have the same argument: cryptocurrencies have no intrinsic value because they are nothing and are essentially lotteries, speculation, and so on.
All those who criticize are often themselves involved in the crypto-industry in one way or another.
Some, like Ray Dalio or Peter Schiff, invest in cryptocurrency. Others, like Warren Buffett, do business with companies that deal in BTC.
