That doesn't seem to be happening if Bitcoin keeps dumping like this. No business can be stable if a currency backing it up is not stable itself. So I don't think anyone would risk adopting a currency for their business that can turn their $20m to $10m over a night. Though it can go up to $40m as well, but that still doesn't vanish the risk it carries.


That rule doesn't apply for business operators I guess, and doing a cryptocurrency business without being taxed is not what Germany allows, but it is just that if a person uses cryptocurrencies as a mode of payment is not taxed for doing so. As, the article says that if an individual is trading cryptocurrencies in their own name will receive a tax exemption, while the exchange where the trades are being done won't receive any.
So, maybe someone would want to go for a shopping trip to Germany, but to start a business there, I don't think that is good idea, as doing it in your own country and doing it there makes it no different.
