I don't know if it is only me but I hardly access any exchange through their website as they are banned by our government. Binance, Kucoin, Bybit and even Bitget websites are not accessible through their websites and the only way of access have been their apps so I don't know if yellow card was accessible before through their website as I have not used my account in that platform for a very long time since I made it.
Yes it's true that the URL of those top crypto exchange are all banned here in Nigeria, and that's the reason why you can't access it through your web browser, but as for Yellow card, I think the site is very much accessible through both web browser and app, and I'm still very skiptical on why should they want to block their URL and only make it accessible through the mobile app, because this is actually a red flag for me, of which if I was to have an account with Yellow card, I will just abandon it till further notice when everything might have stabilize. Because I actually see no reason why they should want to block their website URL, simply because they claim they want to offer better services on their mobile app.
