We don't know, we can't tell it perfectly on what exactly going to happen but we can speculate base on the scenario's where are we right now.

Seen this comparison through a chart and it's likely history is repeating itself. The first wave that happened before the first contract of bitcoin futures closed and I assume it's the big correction for this year if not, the big correction that chanpinchen is saying can probably shake out not only those weak coins but the whole crypto market.
