In crypto currency, Never regret anything.
No point in looking back and saying only if I had done that. Or if only I had sold earlier, instead
Realize you made the best decision in good faith, for every reason that made sense or did not make sense at that time.
Now it is time to let it go.
Focus on here and now.
Thats where success lives in crypto currency
I agree with your opinion that one need not to regret on any decision one must have taken in the past, this because, such decision was the best decision at that point and we should all move ahead because looking back sometime can affect our current decision.
