Dear friend,
It is very hard to find a good ICO to invest because there are too many ICO projects be advertised day by day. So how to choice an ICO what is really good not a scam? I think we must be careful when study a ICO before invest in it. We must collect data about that ICO project,  for example: address of headoffice, technology be applied, the possibility, check the feasibility,..... There are many thing we must to check. And somtimes we need a little luck.
