No way crypto is going to replace stock market, crypto and stock market are two different things.
They will coexist.
Now if you said replace the Forex, then I would have said maybe..
Yeah no way , but forex player and stock investor could move their fund to crypto in the future ,
Crypto nowadays still has lack of trust , common people even consider crypto currency as tons of scam scheme ,
It's indeed there's some bad people involve to take an opportunity scam other people behind crypto currency but mostly cryptocurrency is so legit ,
We just need more time to make it really happened.
