Everything in life has past, present and future. Some of those who invested into some coins while their prices were higher, should try as much as possible not to dwell much on it, because if we continue to bother ourselves about the past loss, we will not be able to see the opportunities ahead.
The crypto space is full of opportunities, learn to find those alternative opportunities of earning tokens and explore.
That which you think might be a loss at this time, can give you huge profit later on in future.
I think that those who dared to buy bitcoins at $20k will not find enough comfort in your words, because we must always keep in mind that during the last years bitcoin became for many a highly speculative investment instrument and many took the risk in late 2017 motivated more by the desire for wealth easily and quickly than by a true interest in technology.
Therefore, after a year of the great speculative bubble, the great majority had to be forced to learn the lesson and undoubtedly today they are dedicated to other things. Actually I think many still hold their coins in the hope of a gradual recovery, but I think the vast majority discovered for quite some time that life goes on and does not stop for the pain of a great financial loss.
