I think crypto currency market will never survive due to several reasons. I will not go into technical depth, you all knows what I am saying, so its better to get out from this before too late.
1- Crypto not a decentralised its truely Centralised by big whales and manipulated, controlling prices according to theirs mutual benefits.
EDIT: 11-08-2018
2- Golden period of crypto has been over. Its declining to an end, I must say "Bigning of the END".
Big whales controlling and manipulated this crypto market. They are always in win win situation, and people like us don't understand their tricks. We can't even imagine what is going on behind the scene but just making us fool. They are "MAFIA" or we can call them "GODFATHER" of cryptocurrency.
So that's why I really hope if the bitcoin ETF isn't approved, by the US SEC. The point's that the cryptocurrency can be kept away from the manipulation of the popes, because we prefer if the cryptocurrency's driven in a natural or pure way. Unfortunately, cryptocurrency doesn't get supervision from the central authority so manipulation can occur at any time.
We think the Golden Crypto period will still occur only the time's just we don't know.
