I know that already. Is there any other applications to this service I can use?

So I am currently using this site called OKEx since a friend told me that I could use it for trading crypto. So far the site seems rather mundane, is there anything else to it?

I’m rather new to trading crypto and I seem to be looking for places to trade crypto. I really don’t know where to trade and there are many places that show up in ads wherever I go on the Internet and I really get overwhelmed by all these places. Do you guys have any suggestions on where to trade, because I don’t and I really want to start trading
