There is always sad news and good news for BTC. The government always treat BTC bad and the enterprise treats BTC openly. Like in China, there is a policy that will ban mining in the near future. But we know the Chinese government is using blockchain tech internally for the B2B finance in the limited area. The government don't want to deploy cryptocurrency in B2C too fast so they may lose control for the financial system. Some government like US or Japan may set up the policy to control strictly on BTC which I think will be a better way for the blockchain industries development.
Interesting ideas, only things I consider is the cost for the delivery. If you want to expand the business, you should service more people, will there be enough business for you if only for cryptocurrency.
