I like Binance's UI/UX design. Binance offers lots of services compared to its competitors, so I imagine that in such cases, it's very hard to have a good UI/UX design but as an experienced designer, I would say that Binance does well.
What offers did Binance have that other exchanges do not have? I doubt what you posted because I see nothing special in Binance than having higher customers. But maybe I am wrong, you can list the features on this thread for us to see.
Binance has options like Launchpool, Megadrop, Cloud Mining, BNB chain to build dApps, Charity, news room, multiple advanced earning possibilities like fixed and flexible stacking, ability to become a liquidity provider and etc...
In my case, I use Binance very often to trade, but unfortunately, I only use it on my computer and not on my phone. The reason is very simple: the app is not at all user-friendly. When I want to buy an altcoin because I saw that the price will go up, it takes time to process the chart. Then, if I accidentally exit the app, to log back in and see the chart for that altcoin is a headache, it takes a long time. That's why I don't trade on my phone, I just check the prices on my phone. I think the Binance team could improve the app.
It's funny that we find the exact opposite attractive on Binance. I can't trade on a desktop but you can, I can trade on a smartphone but you can. For me, their desktop UI/UX is very complicated. It's very easy to read charts on their desktop platform but it's very confusing to buy/sell the coin and to set the stop-loss feature. On a smartphone, it's very easy for me.
