Do they ever work in crypto? I mean newbies trade trash tokens with a market cap below $5m and they plan of making money with technical analysis, seriously? Even Bitcoin can be considered as a low market cap asset now.
having a low market cap is not the reason why trading those tokens is a bad idea. the fact that they are purely pump and dump coins makes trading them a bad idea specially for a newbie who is not yet familiar with trading or with the market itself.
otherwise if these coins weren't 100% manipulated they could have been good choices. but now you only have to know how to go around pumpers and make your profit before they cash out (aka dump) otherwise you get stuck.
