So many things are in a bubble right now. Cryptos look like they are about to have a huge bull run and yes, there will be corrections but any bear market in cryptos will be short lived for the ones that are solid.
Decentralized blockchain currencies and defi transactions are the future. I don't think cash is going away but I certainly don't think cryptos are going away. Big institutions are manipulating short term moves in the cryptocurrency markets so they can accumulate their favorites.
It's a risky market to be in so obviously don't spend money you can't afford to lose.
I have small positions in the crypto platforms I believe in and hopefully that pays off.
