Why did the price crash so hard?
Someone dumped 25 BTC of BCO in one day...
Being smart and selling gradually over a week would have netted them 20-25% more.
Maybe this happened because his staking period has ended, and wanted to get out as fast as posible from Bridgecoin project and didn't care too much if he may crash the price or not. But I agree he/she was not smart enough to sell in stages, so the price can recover a bit after 1 BTC sell for example, he could make more Bitcoins out of it.
I think he probably wanted to get out from Bitcoin as fast as possible as it is rapidly tanking towards 3K and below. Otherwise he'd sold BCO in a more slowly and profitable way.
