and Safemoon on pancake swap. Send cardano (ADA) to binance.us. Then enable your Trust Wallet to show the two Cardano (ADA) wallets. One will be the CardanoBEP2 wallet, and the other will be the Binance-Peg Cardano (BEP20) wallet.
Send your Cardano from binance using the BEP2 network into the CardanoBEP2 wallet.
Once its in your CardanoBEP2 wallet, you can swap it to the smart chain (Binanc-Peg Cardano BEP10) wallet.
Go into pancake swap and buy Bonfire or Safemoon the same way you would with binance smart chain.
You'll still need a little BNB to pay for gas fees, but you'll only need a few dollars worth of it and the bulk of your investment can come from Cardano.
Anyway, I've done it a few times now and it was a nice workaround when most of my BNB was tied up and frozen in Binance...
