Is bit coin or crytocurrency a wise investment?
No.
Even the few actual money managers who suggest allocating some amount of your assets to crypto place an upper limit of 1% of your assets and the rationale is FOMO (fear of missing out).
The blockchain was a real breakthrough idea. An immutable, distributed, publicly verifiable ledger is a brilliant idea with untold utility. Will bitcoin really be the specific technology that's utilized by financial markets? Will ethereum, ripple, bitcoin cash, litecoin or whatevercoin rise to real promanence? Will the existing financial markets arrange their own semiprivate networks to utilize distributed ledger records? It's hard to know. But I do know that I'd bet everything I have that I will not be buying coffee with bitcoin in 20 years.
