But if you have a more wider and longer view on how long you should hold, that profit might increase more. We want more people to hold more bitcoin. And if you are capable of buying now, you have to do it. It's likely that we're nearing to the peak of it once this year ends, no one knows how high it will be so if you're going to buy right now, make it sure that it's a money and amount you afford to lose and hold longer if the market didn't go along with your expectations.
