A an ICO marketplace project called Menlo.One is creating a platform where you will only be required to prove our identity once for KYC requirements. This mid-July, it's going to launch its token sale. When it goes live, investors will be able to buy different tokens within a single platform! I really think that this will change how we investors view ICOs since it will make it very easy and safer.
