If you are looking for safer ICOs, I would go with any of the currently circulating Casino type ICOs that let you participate in their Bankroll. BetKing was one that I still have in mind. Casino bankrolls are almost guaranteed to make good profit simply due to the nature of statistics. If you stay invested long enough you can not lose here.
Then there's S3ntigraph, which may not be the most profitable in the short to medium term. However, if the team delivers and manages to get governments on board, then it has the potential to change the world for the better in the long term and could put out decent profits in the long run as well. This one also has a staking system (e.g. the longer you hold the more rewards in the form of WAVES you will get). I will be putting some money into this one regularly and never sell. I really want to see this one flourish and the dev (who is a Mathematician like me), seems quite capable and enthusiastic as well. This one is probably not going to make large profit, but if you have some money to spare it would be nice if you could park it there for 5+ years. In the long term it could return some money, but to me it's more about the utility that it could provide.
Then there's AiCoin, which uses Machine Learning algorithms to trade Cryptos, ICOs and traditional assets (think stocks, bonds, etc). The trading bot has been running for about 6 months with a return of 120%. Do note that the May boom contributed to this, but there will be more booms of this type. It's hard to say how much your investment will increase, but unlike other ICOs it's safe to say that you will be making profits. This one has slightly more risk than Casino bankrolls, but far more profit potential. If you want my referral link for this one, please do send me a PM, I would really appreciate it.
thank you i will check it
