How would the community feel if an ICO in the US complied with the SEC, FINRA, and FINCEN regulations, and got the nod from the SEC, to run the ICO? Obviously everything would be spelled out and transparent to the community in the whitepaper on how the company would run the business and how the funds would be distributed. But if the US Federal government was ok with the ICO, would the community invest? (obviously if they were interested)
Well, if you had the approval of SEC to do an ICO then obviously people will be extra incentivised to invest in whatever idea you are trying to market to them. However pretty sure starting ICOs in US is already legal anyways, and you don't need the explicit consent of the SEC to do what you want to do.
I would personally stay away from ICOs for the fact that most are projects with no real value behind them. All they want is your money, and when they get it, they disappear fast.
