I have learnt a lesson: we must secure our profits during a bull run. We must have a goal about our holdings and need to set a target where we have to sell. Otherwise, like me, you may regret it later. I am holding a couple of major altcoins like Solana and Ethereum. A few days back when Trump launched his own token, SOL was pumped hard. It was nearly $300, but a couple of days ago it had dropped $117.
A friend shared similar complain about how he had to lose on taking better profit than what he recently took after seeing that he's losing more after that trump effect pump on many cryptocurrency which he refused on selling even when he wasn't targeting on a long time holding since it wasn't bitcoin he was holding.
Anyway, we learn every now and then from market events and having to regret about them wouldn't solve a thing but we just have to not let it repeat next time and opportunity of this nature presents.
