In the long term you have to hodl and come to terms with the fact that is only a temporary loss.
Yeah, that percentage is just temporary loss, a paper loss and it will become a real loss when the actual sale happens. But as long as there is not, it's a big hope that the recovery will happen again.
That's the gist, the status and the tradition Bitcoin has acquired will not allow it to see ridicule for too long. Even if it falls so much now, over the years, you may still see it at a high level that would have been multiples of the value you thought it was hopeless at. This was what I told someone who faulted the last 130 BTC purchase by Michael Saylor on March 17th, though Bitcoin has sold ever since then, but for how long? In the next few years, Bitcoin may be above $150k again, he must have made about 2x of his money by then and it keeps going like that.
