What are the upcoming cryptocurrency ICO's with greatest potential?
I'm not join with ICO anymore, to much lost I get after replace my money. ICO is new way to collect fund from us and use it to develop their program. It's good concept but when they fail we also lost our money. Specially at this moment, I'm not recommended any ICO to join. Market is not stable and bitcoin has lower price and my money stuck with it. Think again and good luck with you.
Ive got some words from you.. Then If you are not participating ICO now?? And, what do you do Now?
What I learn joining ICO's that if you Join In ICO's Think first how much you want to lose.
