IMF supports crypto, but it does not support Bitcoin. If you are the owner of the Fed, a banker with a monopoly over money creation and control over finances, that gives you unlimited power. It is natural that you dont want to support competition from decentralized money like Bitcoin. Crypto is supported because it distracts many people from Bitcoin. Crypto is a distraction. Crypto is a return to fiat, and most crypto serves one purpose,to maintain fiat currencies and pollute the space through USDT and USDC.
I agree with your point. The IMF supports cryptocurrencies, but it doesn't support Bitcoin. It is trying to support centralized stablecoins like USDT and USDC, which I consider worse than banks and fiat currencies.
But I disagree with you on one point: generalizations shouldn't apply to all cryptocurrencies. There are cryptocurrencies similar to Bitcoin in terms of decentralization and privacy, such as Ethereum (ETH), LTC, Monero (XMR), Dash (DASH), and Zcash (ZEC), although they are, of course, not comparable to Bitcoin..
