I don't know which others, when i come first I look at coinmarket cap and learning a detil the coin I want to buy.
My friend ask me, what coin he should buy , but I not really sure for now because I'm entering cryptocurrency 3 years ago. Too many coin right now that make me confusing
for a beginner, I think what you do is study the market movements and also learn the coins you want to invest. I think for a beginner should follow what you are doing.
