Cryptocurrencies are now equal (treated under certain circumstances) to legal tender. This is the statement of the German government in a new 27.02.2018 VAT law. I think this could be the way how G20 will handle cryptos for the whole EU.

- Hofbraeuer
- Converting crypto to fiat is VAT free
- Mining is VAT free
- in game currencies are not equal to fiat
- exchanges are VAT free now
- Cryptocurrencies are equal to fiat if they are used as payment
The part about legal tender is wording in the legal document. So, this doesn't mean you can go to the next supermarket and demand to them demand from them to be paid with Bitcoin, which is actually a good thing.
