If you knew it that Bitcoin is here to stay probably you'd just keep it and won't do anything but to keep on holding. I understand that many are going to sell at some point of their lives but if you're still contemplating what to do with your holdings then, it's just best to hold it for now. That's the reason why many have sold too early because they do not have a concrete plan whether they're going long term or just short term. For the long term investors, they won't mind what's happening to the market and they will even accumulate more.
