Thanks for the feedback. There is no intent to move it to a centralized domain name / hosting as the hope is that users of the protocol run the site from their own localhost server. If they do that, it makes it more difficult to censor the protocol.
Technically speaking, I don't have an idea with that but if that's for the good of the users then that's a good reason. I've only suggested as a part of the users that has a first impression whenever we see a domain that's not very familiar, although I'm familiar with github.
There is no minimum trade size to use the protocol. What you are referring to is an open offer to buy DAI using fiat. Anyone can create an open offer of any trade amount. The mail method on that offer means the desire to send fiat by mail in exchange for DAI.
Ok, that means that using fiat > DAI, there's a minimum amount for purchase. Whilst, using crypto to crypto transaction, there's none? I think I've understood it, thank you for that.
