What you think will happen:
- Ukraine will make fat stacks from all the people who care about BTC. Crypto-libertarians will rejoice, issue fifty billion ICOs, and Ukraine's GDP will exceed that of the rest of the world. BTC will go to the moon, and anyone who didn't get on that train when its future was in doubt will be starving to death in a ditch, or working as an indebtured servant, soldering mining rigs for early adopters.
What will actually happen:
- Any Ukranian bank that touches BTC will be barred from doing business in USD. For a bank, this is as good as suicide.
- Any intermediary that exchanges BTC for a local currency (Hryvnia), without touching USD will be barred from transacting with any Ukranian banks, that don't want to be barred from doing business in USD.
- Anyone trying to use Hryvnia for any international transactions will be subject to strict AML scrutiny, because it is a well-known intermediary currency for laundering BTC. The burden of proof with AML is on you, not your accuser.
- The Ukranian Rada will quickly come to its senses, and, in order not piss in the cornflakes of the 99% of its citizenry that doesn't give a shit about BTC, will ban it, and stop being a pariah state in the world of international finance.
