if you bought bitcoin just to make a quick profit then sure, sell and get out now. you have already gotten the "quick" profit anyways.
but if you are not just looking for that quick small profit then obviously you should hold for long term. these short term rises and drops are not for those who are not traders. and I don't think you are a trader or plan on starting to trade so selling now is not really a good option if you ask me.
Good advices, cause its not just one. Quick profit or holding for future is something that I ask myself almost everyday. Price of bitcoins is making new records and in next few days that will not stop, until this new hard fork price will go up a little bit more.
Good time for buying is now when we know that price will go up and touch 6.000$ in next couple hours, and maybe 7.000$ in next couple days. Be careful after fork, maybe we will see some dumping and price drop.
I must add : And if you really about to make good money, try your luck in trading atls because now is perfect time, they are dropping like crazy. As seen previously they will also recover when situation settles.
Bitcoin will continue with price rise and who know where are the limits. Just do not fall under influence of some people who promoting other ideas and trying to disrupt our success.
BCH supporters becoming very aggressive in their efforts to proclaim BCH as only rightful, real on Satoshi principles - "BTC". Prepare yourself for best FUD you've ever seen..
