In my opinion, the coins that can still stay green when the market drops since December are MANA, Sandbox, MATIC and AAVE, of course not every time they are green because of high market pressure sometimes red, but in general it is calculated that since December 4 the coins have increased by more than 4% , and I will hold it for a longer time.
Just because of that you choose that Altcoin for you to hold in the long term ? indeed in general or basically nothing wrong or not funny, but if only that thing can make you so sure to hold it for a long time, it's actually quite risky, because it might not happen again at a different time or in the future.
