"Since Bitcoin appears to be neither suitable as a payment system nor as a form of investment, it should be treated as neither in regulatory terms and thus should not be legitimised. Similarly, the financial industry should be wary of the long-term damage of promoting Bitcoin investments - despite short-term profits they could make (even without their skin in the game). The negative impact on customer relations and the reputational damage to the entire industry could be enormous once Bitcoin investors will have made further losses."

"I’m a major skeptic on crypto tokens, which you call currency, like Bitcoin, They are decentralized Ponzi schemes."

"There will come a day when you wish you sold #Bitcoin for $20,000! Take a look at the historic chart to see how far of a fall is possible, if you are interested in risks associated with an unraveling Ponzi scheme."

"Bitcoin is nothing more than a string of digital codes, and its returns mainly come from buying low and selling high... In the future, once investors' confidence collapses or when sovereign countries declare bitcoin illegal, it will return to its original value, which is utterly worthless."

"Bitcoin's washout will not see a fast comeback. The decentralized dream has been exposed. Connect the dots and act accordingly."

"Bitcoin has pretty much lost all its gains throughout the pandemic and hit a new horror low that will make history."

"Previous declines didn't involve anywhere near the total market cap lost during this decline, nor did they involve massive leverage. This crash is just beginning. #Bitcoin will not recover."

"As cryptocurrency companies come under closer scrutiny, they will start looking less representative of the libertarian ideal on which Bitcoin was founded and more like the ageing banks it was meant to replace. At that point, we might start to wonder where its value comes from. If a couple of companies have the power to crash the entire market, Bitcoin does not look so free after all."

"Bitcoin will never be a safe haven asset or a central currency."

"Bitcoin is down 50% since November. You risk losing everything."

"By its very design, blockchain technology is poorly suited for just about every purpose currently touted as a present or potential source of public benefit. From its inception, this technology has been a solution in search of a problem and has now latched onto concepts such as financial inclusion and data transparency to justify its existence, despite far better solutions to these issues already in use. Despite more than thirteen years of development, it has severe limitations and design flaws that preclude almost all applications that deal with public customer data and regulated financial transactions and are not an improvement on existing non-blockchain solutions."

"My very humble assessment is that it is worth nothing. It is based on nothing, there is no underlying assets to act as an anchor of safety."

"It’s terribly clever, but a pointless, busted bubble."

"Digital currencies sought to replace the financial system with one that was faster, cheaper, less under government control and more accessible to the poor, but they failed."

"So cryptocurrencies are no longer making anyone rapid fortunes, are no longer protecting against inflation, and governments are working out how to find them. What exactly is the attraction? They are clearly little more than a pyramid scheme: machines for redistributing wealth from players who are late into the gold rush to those who were early. And like all other pyramid schemes, they have a brief and finite life. Many of these new get-rich-quick schemes – like NFTs – have already come and gone. Cryptocurrencies face not so much a rapid crash as a slide into nothingness."

"Of course I hate the bitcoin success. I don’t welcome a currency that’s so useful to kidnappers and extortionists and so forth, nor do I like just shuffling out of your extra billions of billions of dollars to somebody who just invented a new financial product out of thin air."

"Crypto assets are no different from a classic Ponzi scheme where a steady stream of new entrants pays off the older members. It all depends on greater fools joining the rush to participate because prices are rising. Today, the greater fool is wondering whether to buy Tesla and Ethereum."

"Not only is Biden authorizing the regulation of digital currencies, but he is also instructing to move forward with a central bank cryptocurrency. Once that is done, all other cryptocurrencies will be seized and folded into the government’s crypto. For all of those who said Bitcoin replaced gold and the dollar, if they didn’t bother to look at a chart, it has been declining since last November."

"#Bitcoin won't be around a decade from now."

"People still fixated on #Bitcoin are living in the past. #Gold is the future. The last ten years are irrelevent to what will happen over the next. This is gold's time to shine. Bitcoin's candle will soon blow out. Bitcoin HODLers who fail to grasp the change will lose everything!"

"I wish it had been banned immediately. I admire the Chinese for banning it. I think they were right and we were wrong to allow it."

"Attention #Bitcoin buyers: This could be your last chance to buy Bitcoin above $40,000. So hurry up and buy those high-priced Sats while supplies last."

"Originally, Bitcoin was supposed to be a currency. Then, it was supposed to be a hedge against inflation, a sort of digital gold. But as the great crypto market crash of the last three months has begun to unfold, it’s started to look like something much more mundane: a crappy tech stock."

"In 4 years, bitcoin will be a traumatic memory."

"You’re going to see a lot of movement in terms of doing authentication and insurance policies and real estate transfer taxes all online over the next few years, making NFTs a much bigger, more fluid market potentially than just bitcoin alone."

"I feel safe saying that, when history looks back in hindsight, it will see crypto as a gargantuan bubble that — as capitalism always does — wiped out the finances of tons of small people who could not afford to be wiped out, and left the rich mostly intact, all because it was able to convince regular people to believe that this time was different. The delusion that salvation from capitalism can be found in new, more clever capitalism is incredibly seductive, and always wrong. Let’s hope that we snap out of it before it’s too late."
