They are some factors which i checked first on new altcoins. First I will look at the project and do my research very careful, for exemple I will read the whitepaper to see their vision and also check for any spelling errors to see if they are really serious or not. Then I will go to their telegram page and talk to the team and also to other investors. And if I feel comfortable enough then I will invest in it. And when the price goes up I will sell, I am not going to hold forever.
