I periodically read reviews of analysts on altcoins. And if I see interesting technology, clarity in the work of the team, then such a project will interest me. But if there is a lot of noise around such a project, then this can be alarming. And you need to check whether artificially increase the popularity of altcoin.
same here. i do also read some information about the specific altcoin that im going to invest. usually i checked if the altcoin has a real world usage because if there is then there is a posibility that it can be sucesful when the right time comes. though i dont oftenly invest on every new altcoin that came out but instead i do foccus more on the classic or the pioneer ones such as etherium .

popularity does not mean the coin is already legit or a scam because that will still depend. ive seen some coins that is popular because only of manipulation , i also seen some coins that become popular because they are actually good coins.
