What ICO investment do you recommend?
Tough one to answer for anyone here, and you ought to be suspicious of people just promoting for their own good.
I'd say, check a few sites like icorating or icobench and try to personally identify with the problem that the ICO is attempting to solve. Does their solution make sense to you? Does it feel tangible?
Hard to say
which ICO I'd recommend you to invest it, but that's how I'd recommend
researching into which ICO to invest in.
