We hope that he already sell it yesterday so he can buy bitcoin again today because the bitcoin price now is down deeper than yesterday. Or if he did not sell it yesterday, he could still hold it again, and don't sell it now because he will not make a profit. The bitcoin price now seems to get stronger than a few hours ago so we can hope that the price can bounce and back to a higher rate. If there is much demand for buying bitcoin, we can wish that the price slowly will increase.
