Bitcoin is uncomfortably close to a decentralized distributed pyramid scheme. There has always been a lot of pressure on people who bought in to crypto to proselytize in order to continue to grow the pyramid. Without those people buying in at the lower level, all the bitcoins that the early adopters got for less money aren't worth anything.
That's not a pyramid scheme, unless you disagree with this definition:
A pyramid scheme is a business model that recruits members via a promise of payments or services for enrolling others into the scheme, rather than supplying investments or sale of products
https://en.wikipedia.org/wiki/Pyramid_scheme
Pyramid schemes are illegal. Bitcoin has a regulated futures market in the U.S. The U.S. government does not agree with you.

"that recruits members via a promise of payments": The hoped-for promise of payment is the sort of exponential increase bitcoin saw between 2011 and 2018. There was also lots of talk about bitcoin and other cryptos being inherently deflationary by design. Near the peak, there were ads playing during the Superbowl trying to recruit members. People talked about the FOMO all the too-cautious people would feel when a cryptocurrency became a worldwide medium of exchange, and you'd have to buy in the future at $1M per coin or something like that.\
...
Your first sentence tries to redefine what "promise of payments" means - you're twisting words to fit your agenda. Hoping for something isn't a promise - its a hope. Nobody makes "promises of payments" to those buying Bitcoin, but if you admit that the pyramid scheme theory falls apart.
So here's a more basic question: where is the pyramid? Every bit of data and software for Bitcoin is 100% transparent and public. Where is the pyramid?
In 2021 the price of BTC reached over $60,000 and is now under $20,000. That's not how pyramid schemes work - they do not give greater rewards to those who invest later, and screw over the early members to the scheme. And this 2021-2022 is not an isolated incident, as Bitcoin has crashed by 80% repeatedly.
It does not promise payments, nor reward people according to a hierarchy.
Regarding promises of payments,
a) Convicted Ponzi scheme ringleader Bernie Madoff did not promise specific returns, he simply delivered high returns for many years. Investment money rushed toward him by word of mouth and from people chasing past performance. If we want to get strictly legalistic, we could say Madoff only committed accounting fraud and should have been acquitted of running a Ponzi because he didn't specify a dollar or percentage outcome. But most people will accept that Madoff
was clearly a Ponzi scheme even if he didn't promise a specific return on investment. Not telling people they'll earn a specific number made him more credible. We can't be thrown off by one optional detail in the definition of a Ponzi scheme, or else we make the same mistake as Madoff's victims.
b) People on Wall Street Bets, Facebook, and YouTube were literally drawing cartoon rockets symbolically taking cryptocoins to the moon. They were literally posting pictures of the luxury cars they allegedly bought with crypto gains. Meanwhile the crypto-intellectuals were talking about how whatevercoin was going to take over the role of the US dollar in international exchange, and how each coin could go to at least some outrageous price target, like $100k, $200k, $500k, $750k, $1M - they were throwing numbers out all over the place and extrapolating from 2011-2018.
Regarding transparency, the blockchain itself may be transparent in theory, but what is transparent about how you got your coins stolen, who now owns them, or why the exchange / wallet / brokerage you had to use as a non-technical user just disappeared with all your money? This is where theory collides with real life.
There are over 1M FTX account holders who looked as hard as they could, and couldn't spot the reason they were about to lose their entire investment
in what was the world's most legitimate looking exchange! They got conned, just like the victims of dozens of other hacks, collapses, pump and dumps, etc. It's fair to assume lots of people only think they own the coins their financial helper displays on the screen, and that the actual coins were sold long ago or the money laundered long ago. It's easy to post a fake number of bitcoins owned on the screen.
It's odd to say the various falls in the value of Bitcoin prove it's not a Ponzi scheme. Eventually going down is exactly what Ponzi schemes do. Enron stock went up and down for a while, until it went down to zero. Yet I'd say price action is the last thing we should be looking at, since it appears that more than half of all these "transparent" price discovery trades are fake:
