Xrp , eth in my opinion is good to invest small amount in. Unfortunately I can tell you to invest in IEO it might not turn out good. A well known and existed project and top projects isn't a bad idea to invest. The choice is yours to make.
How many time I have talk you about bad investment for buying Ripple because more than six months ago price Ripple always down, for ethereum maybe good choose because can back with higher price during bitcoin can up later, for Ripple not have choose again for investing because never take your risk with coin not give you profit.
