The original layout was designed by man who was born in 1963 and did run his own exchange before it was shut down by government in his country...
A message for the designer, It is really necessary to keep up with the times, technologies develop and improve very quickly. It is not possible to work on the same thing for a long period of time, especially not when it comes to Internet technologies.
What comes to licenses and things like that, it really depends on applicable laws of the country the exchange operates from... Some countries like USA and Germany have stricter requirements than other countries. In some countries it's just illegal to run a cryptocurrency exchange.
You cannot justify how some exchange offices operate without a license, or where there are stricter regulations. Simply, you have to register and thus make your business official. We fight against illegal and fake services every day just to prevent it from becoming a regular practice, and now you use that as an excuse.
KYC and AML go hand-in-hand, most countries require complying to at least AML, but you can't have AML without some kind of limited version of KYC, even if a lot of cryptocurrency traders think KYC is just a government conspiracy, as some countries don't even allow storing KYC information for verification purposes, so the information must be re-collected each time and immediately verified without any delay.
You are right about AML and KYC, but, as a non-registered business, where do you get the right to demand any documents from potential customers? To whom do you justify the legality of funds, if you yourself are illegal? Who is responsible for monitoring your business?
