Whatever the reason they did it... the inevitable outcome of situations like these is the big accumulators accumulate, while those who cannot afford to hold on to their assets sell on at a loss.

Every 'crash' of any kind is followed by institutional accumulation like this. The pie shrinks, but those who can afford position themselves with larger market share for the good times.

After every bubble more capital is concentrated in less hands.

So HODL or trade your way out of it (risky).
