Sell if you buy more, now the price is at $2800 now, a decent profit there, if the price drops again, buy it and wait till the price recover and then sell it. It depends whether you would like to be actively trading or treating Bitcoin as a passive investment. If passive, just keep yourself away from the Bitcoin price (to minimise risks of heart attacks), and check back again aftter a year. Smiley

It is not too late yet to hold BTC
