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
You must not regret holding at all. Coins like Paragon, Cardano and Stellar are worth investing in and their projects are great. They shall rise very soon in value. Hold till then.
