I must admit that many altcoins would do well this year and its best you don't get stuck holding any if them, I'd advice if you want to hold anything go for bitcoin it's the best and you won't worry about price dump much, altcoins I would have recommended are already up, bnb, eth im not really an altcoin Person but sure keep buying.
As long as this altcoin still has a team that works very well and always develops the projects they have, the altcoin will increase in price because there will definitely be investors to provide support. But when the project being developed is not very popular with many people, it will make the price of this altcoin not has the power to raise prices.
