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. 
It takes time before you make profit on those new and promising token, and most of the time they failed to reach their target and they ended up as a scam project. Be ready for the risk as you may not see profit here right away, the waiting time might discourage you to support the project all the way, just have a spare money for this where you can afford to lose.
Small projects and less popular tokens are facing a lot of challenges, this is not a guaranteed success.
