Have you thought about the Point of sales industry ? Steem is very unique in the way we have very cheap extremely fast tx. If you already have a way for cash to come in, I think a lot of businesses could use data services only our systems provide. I already have a website our community helped to code that enables Steem e-commerce with 0% fee. Coinbase has a solution as well. I've been using/testing. Blockchain PoS systems can be used along side Fiat .The solutions I see from say Apple or wechat provide none of the features that the blockchain can. With Steem we have our Public key , this key can be used to decrypt memos. So imagine a basic receipt logger into the blockchain using private memos. This is just one of the things that will be built with blockchain technology. The possibilities are quite endless. Good luck with Metal , I look forward to having more competition with e-commerce applications and crypto-gateways.
