I think in case of taking it it will be stopped or reduced a bit. In the case of point-of-sale and payment gateways, I have been able to mention explicitly. Governments do not allow and do not allow stores, shops, sole traders, etc. to continue to sell goods or services without any duty. Regardless of where you keep your money or what you are doing with it, the fact that you are conducting any business and transacting in their country / state is enough to keep an eye on you. Yeah Al that sounds pretty crap to me, Looks like BT aint for me either. It would be very foolish to try to “hide” it from them at the risk of fines.
Similarly, saving a lot of “offshore” money will draw the same kind of attention that one day you want to cash in and spend it. Governments will always see and demand their cuts. This is not his fault at all, all privacy coinage is something inherited from real world use. It will be interesting to see what steps governments take when it comes to the use of privacy currency for day-to-day transactions.
