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 have already read somewhere this saying of yours, and it is really insightful and encouraging for me. Because doing that you will be more successful than 99% of guys who would be just considering about the previous and not improving.
