What's next? Here is Room-House.Exchange as a part of R-H.City. What I'd have done next, is A. merge two programs in one (currently, Eth coins -> RHC is one VueJS program, RHC->Eth coins another VueJS program). Merge better in React. B. have to use a reliable captcha to block the bots. First TX starts after a human captcha confirm. C. add BTC suite coins like Blackcoin. And in the end, you have 100 coins to 100 coins fully automated swap Exchange. No registration, no KYC. But I can't do this whole thing alone, without frontend React people. I have ready Perl checker scripts.
