Actually prediction is not possible in crypto market but I can give some extent of making profit if you follow following steps.
First of all make an account on exchange which is quite popular among others like binance, houbi etc ... When you wake up on morning first of all check coin which is one highest volume and invest in that coin than you have to wait till afternoon than sell it.
I usually do it yesterday i made 1000 USD profit from binance.
one of the coin went on 130% in just 4 hours. I invested 950$ into that coin and made profit from investment.
