Don't marry the bag, sell it when you know that you've multiplied your profit to a staggering percentage, you will always be able to get back to bitcoin even if you sell your bitcoin because the price will eventually correct itself so just keep a watch on what's happening on the market and the price of bitcoin so you know what to do next. If you're unfamiliar with the saying that I've said, I'm basically telling you to sell your bitcoin when the price is pumping and the sentiment of the market is that it's nearing the peak, aim for that peak when you sell.
