That whale did.

Actually we can predict the dump will gonna happen as since dec'20 until Apr'21, bitcoin price always going up. Then we just need to spare some of our money to BUY more when the crash/dip comes like many days ago when bitcoin at $30,000. Many sure got rekt, but others even laughed because they are waiting for this moment to buy some promising coin with cheaper price
