cost? scam? believe? Data cocoon room? This is probably why we are afraid to buy new coins. So, starting tomorrow, I plan to take the first step to learn about an unknown coin. Everyone is welcome to recommend, and the flag is set here. 
You are trying to jump into an ocean that doesn't have a bottom. How many tokens will you study about every day? I don't think you will do more than launch new projects every day. Not only the scam project but there are many promising projects everyday that are worth noticing. If i had enough funds i would have invested in all of these projects, even if it was a small amount. But its a learning opportunity to study all these projects and their concepts, which is really amazing.
