It would be really great if you tell us the names of cryptocurrencies, which you are going to get stocked up as the year goes by, as you said. Because there are really many projects, which are good for preferring. But any way l think also that, it is more profitable to invest in altcoins, which are in top rank like ETH, BNB, etc.
The 5 project I mentioned earlier are in the top 50 and they are
Ripple
Cardano
Tron
Stellar
Hedera Hashgraph
Good research has been done on them and they are still below 1$
Good research for what? ripple has become the worst choice these days, lack of volatility and multi-billions pre-mined coin that is not yet distributed to the market and it will soon come to the market. This is the worst coin that you must not put it in your list.
