This man here is just offering his opinion, it's up to you to make the decision.
How can you not see the problems cryptos are having? They have almost no practical use right now. The only reason that fiat currency is not flying around hundreds of percent daily is because it's in constant use by billions. The use is what creates stabilty and without stability there won't ever be any practical use. Cryptos are obviously boiling over right now, and this is good, it needs to crash hard for it's future.
Let us pray that it crashes earlier rather than later, because if this bubble pops and too many people lose all their money, then people will start to hate crypto and any attempts at decentralization. Without public support, the idea of free crypto will die and we might only see banker coins in the future.
