All in all, lessons learned, I'd learn to be patient and think twice before passing my judgements, what was your experience and are you taking any step to redeem the good ol times?
We don't need to regret everything that maybe in the past we couldn't do, at that time maybe we didn't have the opportunity to do it, but for me if we do crypto trading there are no regrets, currently crypto trading is still good to do, except: regret not having time to buy doge as you said, but it's useless the journey has reached the destination.
Once again, do what you can do now for yourself, for example crypto trading might be better, if we hallucinate the past, it is impossible to do it anymore, there are many ways that can be done in the crypto world.
The one who only mourns the past won't be able to see the future ahead of himself, bright or not.
But if a person would work for it, it would surely be bright and a lot nicer than what we described in our posts.
OP, stay strong.
