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. 
I encourage DYOR behavior in this market anyway. But I don't have certainty with projects that get little attention, instead my strategy is still bitcoin and the top altcoins, in fact the price increase from them is enough to make me feel satisfied in the portfolio personal investment. I'm not a person who likes to look for uncertain opportunities with things that many people consider x100 x1000, of course they exist but it's not much different from betting games, risking can bring big profits, but also puts you in a more risky position.
