Luck came unexpectedly, if you know and sure what is your next move, when to buy or sell and make profit, then you can't call it a luck, it's a skill. But if you don't know or no idea of the above mentioned, then just buy or sell of nowhere then make profit, then that's a luck.
I hodl, but after the dump, obviously i convert it to stablecoins. You need rational reasons to sell don't just believe something that it will bounce back when most crypto is in red.
