Americans are ready, but ICOs are not ready to invest. In addition, it makes more sense to choose the safe STO created by the SEC. In any case, 3.75% of American population is not small number, and and it would pleasure to us that these figures are correct.
SEC is not created STO but SEC just release regulation frame work for that, It's a lot of number but the strict regulation in USA was creating a very bad situation for them all. Just try to hope there will be a market that will be free from manupulation that makes SEC can approve it.
