I do not know why! I only think that Ico project is a more modern Ponzi method right now. 
How about you, YES OR NOR ?
A lot of ICOs are just scams, the main sale which are nothing but setups are used to compensate the presale buyers who have gotten huge discounts only to dump on unsuspecting ICO participants. Meanwhile, many are just there without any MVP and track record. My advice is to be extremely careful of ICOs. More than 90% are just scams How about you, YES OR NOR ?
