IvyKoin has a great idea, They are offering better KYC and KYT option but IvyKoin is still unknown to the vast majority. I suggest you invest on ripple instead of Ivy. If you want to take a risk go with Ivykoin, on the other hand, if you want to play more safely prefer ripple.
I am ready to take risk. But How much ROI may I get?
Nobody on this forum can answer that question for sure. As I mentioned, people do not have much information about this currency. If this currency is discovered and attracted by investors I am sure that this currency gonna improves in the market. If the situation as I said happens, you have a good chance of making a good ROI.
