Smart Contract Issuance basically means ETH (example) in-> Token Out -> you would need to write a smartcontract.
The problem then ofcourse, perhaps you get an American, Canadian etc purchase....
Becomes an absolute nightmare...︀
UK Law doesn't have any issues with a ICO, IDO etc...
All completely legal, but︁ for obvious reasons you move to Cayman, Bahamas, BVI etc and do there for tax︂ reasons for the company.
In addition you ensure your purchasers don't have dual nationality, are︃ not tax payers, do not have immigration cards for, do not live in the US,︄ are not operating through a overseas corp for a US entity, person etc.
Then on︅ top of that you don't use US Vendors (Amazon, Google, FB, Twitter, etc) -> use︆ Chinese alternatives for technology stack, and where social media is concerned you do absolutely no︇ hyping and you can restrict audience (i.e FB) country wide to block US Citizens etc︈
And lastly you don't use $, CHF or bank with US Banking corporations, CHF routes︉ through SDNY which gives a nexos.
You ensure all marketing, KYC, AML etc routes out︊ those aspects.
Oh and lastly, make sure there isn't a yank working at the APEX︋ in your organisation, if there is throw them under the bus.
~ I read every︌ court docket so you don't have to, to get a understanding outside of the sheer︍ lack of clarity suffice to say those are the routes to market above and it︎ all depends on whether you are unlucky to be targeted because just one American gets️ through.
