As soon as everyone starts shouting about the lowly in one voice and the collapse of the exchanges, then the market will unfold. This will say that those who used to shop earlier started selling the crypt. At this time, large players will buy crypto currency from nervous people, and when bought up, news agencies and TV will begin to generate a positive background for crypto-instruments. A new rally will begin without those who left the concert.
I think no one could predict the exact time and date regarding the recovery of the crypto market, because the movement of the value of cryptocurrencies is always depending on the demand, But the market will always recovers when there's ups and downs.
