It's your own decison and responsibility whether to buy hold or sell Bitcoin now. The rise we saw the last weeks is tremendous and if I would hold some Bitcoin I would probably sell now, wait for the next correction/crash and then buy again. But noone knows when the correction will come. This is the hard part of this game.
Many people ask this sort of question every time; the funny part is that even if they get the same answers, they still keep on asking. I mean, it's your coins, which means that it's also your call depending on what you would best do with it. I think the main consideration here is what's your goal. If you feel that you have the patience to risk holding on to your coins in the hopes that its price would increase, then by all means do it, maybe it would be the best plan because patience always pays off. If you want to cash in now and sell them while the prices are still surging, then no one would say that that's a bad idea because money is still money and profit is still profit.
