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.
It is the right word. We should not dwell on our failures and move on. All you do is experience. Sometimes this experience is unsuccessful, but you can learn from it.
