What type of merchants would use PROOF? For example, why would someone from eBay or Amazon use proof, or are you thinking of something larger scale?
That's a good question. Amazon has stated that they will start accepting Bitcoin in the future, but BTC is too volatile for a lot of people's comfort. This is what I think is hindering massive adoption. Now with Proof's crypto-fiat market activity and awareness is key to the success of their AMP. They will use crypto-fiat to drive more interest in decentralized markets. They are partnering with companies for adoption from substantial crypto hedge funds like TaaS. I have been reading their whitepaper. lol.
