Wanting to move my crypto somewhere safe

Hello,

I’ve been in crypto for a few years but so far have always kept my btc on Binance. I’ve been seeing the phrase ‘not your keys not your crypto’ a lot and now think it would be wise to move it to my control.

What do people suggest? I’ve heard about cold storage and the nano ledger but I’ve also heard that these have somehow been hacked and people have had their crypto stolen from them.

Can anyone give an idiot proof guide to moving my bitcoin from Binance to somewhere only I have access and control please. Also what would it mean for selling in the future, I presume I’d have to transfer it back to Binance to sell?

Thanks.
