crypto & offshore means loads of risk for the psp/bank/emi; so forget about that that.
you need local connections, so a local entity and local director, shareholders can than be foreign:
uk has︀ a lot of crypto related startups. and Ltd is lowbudget, local and ppl understand it,︁ main drawback is the UBO will be visible.
ch also has a lot of crypto︂ related startups. setting up an AG is expensive, you need a local director (anyways) but︃ the UBO will be hidden.
so you have to decide if you need privacy so︄ much that you want to invest 100K CHF (and have 8KCHF p/y running costs). now︅ if you are gonna spend it on software developement anyways, the swiss route is "less︆ expensive" as you can use the 100K for this. you than only have to budget︇ for the local swiss director.
