You can start looking into Dai which serves as a stable coin using collateral or more generally into Security Tokens (here an explanation on STO https://medium.com/crypto-oracle/prepare-yourself-the-securi...) Those are going to be big very soon!
Security tokens are a Bad idea.
Dai is basically only useful for speculating on cryptocurrencies and so I dismiss it like I dismiss exchange dapps. This whole industry can't be built on speculating on the value of nonces.

I like the legal system. The transactions I'm involved with are already cheap and the non-cheap transactions aren't made cheaper with the blockchain.
