Thanks dude! This was super helpful... I've now got the Binance Smart Chain on my Metamask as well as BNB, CUB and bLeo tokens added.
I've also got some BNB that I purchased on an Aussie exchange... the thing I'm struggling with is actually sending them to my MetaMask. Did you click on the address that is your usual MetaMask ethereum address? The one that is copied to the clipboard when you click on your account name? When I try that one the Aussie exchange tells me it's an invalid address... so close.
