transfer some of my bnb to trust wallet.
If you have a little bnb for gas (like a couple of dollars), you can use Cardano (ADA) to purchase both bonfire and safemoon.
Or sell enough safemoon (again, only like $5-10 worth) to have bnb for gas. Use Cardano for the bulk of your bonfire purchase.
Search my post above for instructions on how to convert Cardano to the smart chain...
