I have this rule for me; everytime that i am bored, i just join a lot of telegram groups, and most time, they are always talking about upcoming ICO's and which of them are going to be profitable.
If you use telegram, just join those groups, they are pretty easy to find and you do not need to be an expert in order to talk to them, you just need to know how to speak in english, lmao...
Most of those sites are getting paid for shilling their own ICO, so do not trust in them, most of the ratings are always paid. If an ico has 5 starts, just start doubting about it.
