I did not buy CAKE specifically I thought it was created when I bought some jindo inu and approved the token for liquidity?
Oh okay I think I'm following it now. Where did you stake the JIND that you bought? I don't see that liquidity pair on PancakeSwap.
If my lower left hand screen it says "16$ and it fluctuates". I though CAKE was generated.
I'm afraid that's not how it works. CAKE is generated from farming and staking. The price on the left was only for monitoring purposes.
I want to trade bnb coins with my wallet. Does the whole thing not function if I have a "zero balance" of BNB on the wallet?
You cannot trade BEP-20 tokens like CAKE on BSC exchanges like PancakSwap if you do not have BNB.
The same how you cannot trade on Ethereum DEX without ETH for gas.
I want to use the Trust for BNB chain and my metamask for eth chain because some coins are cheaper on the desktop denomlinated in BNB and not ETH.
Binance has two chains that you can use.
1. Binance Native Chain
2. Binance Smart Chain - BSC for short
Metamask works on both Ethereum and Binance Smart Chain meaning you can use one wallet for both chains.
