Looking to invest 1-5 BTC in 3 different running ICO's which is legitimate and has good potential.
Do not suggest any ICO just because you are a part of their signature campaign or part of the team (I will comment on this one). Give a good reason please, if you did research share the advantages of the ICO and why you think it is a good investment opportunity.
I can suggest which sector you can target to select ICO that will give you High profit.
Messenger's market is the most important category. (Xmoneta, Telegram)
Education is another most important field which you can target (NTOK)
And the last ICO for my view is KYC.Legal (you can get stakes for bounties). This project will solve problem with identification.
