OK, here we go again.
I see that a huge number of coins are listed as an exchange option. Based on that, I assume that you are a reseller and that you do not use your own funds for exchange, but have a liquidity partner. And that's legitimate.
However, you claim that you are no-KYC, which is impossible if the exchange on your site depends on a third party.
How did you imagine it would work? You don't ask for KYC, but your provider (liquidity partner) does? What happens if your partner freezes funds to a user who came through your application? Do you have a method for solving such cases?
Your provider Changenow, is known for blocking users' funds, it cannot be said that it is an unrealistic situation
Whenever I open the exchange it is in dark mode.
Roochange should change the default settings on mode to light
I prefer and always choose dark mode, so I suggest the default settings on "mode to dark". Now we've given the OP a dilemma.
