As events unfolded (slowly) I've become more interested In working to level the playing field instead rather than running a second business that would require far more investment in time than it would if I was as to operate wholly in the uk. Don't mistake this for lack of drive, I have obligations to my current business which take priority.
Any letter to the banks should inculde a list of all their recent scams and fraud, from interest rate rigging, to mis-selling of products, along with the penalties they've paid.
I presume it wasn't the banks who advised you about this - I wonder how many people know about the situation with Bitcoin?
Regardless, good on you for trying to level the playing field. Judging by nearly every issue of Private Eye recently we need a bit of help cleaning up financial services here.
Had a fascinating chat with a Latvian chap who was telling me how literally every business in the country keeps two sets of books.
