Binance has a very steep learning curve, indeed.

I can recommend, you technically just need three functions:
Account, Market, Wallet (Funds).

On the Account page, you find under the small „mannekin“ in the top right corner when clicking on your E-Mail, you can set up things like 2FA or change Password.
When clicking on the BTC-Balance, you can get to your wallet where you can deposit and withdraw.
And „Market“ is the function where you can buy and sell. Simple as that. :D

Everything else is beyond my expertise after five months of Binance. :D
