I cannot comment on Connbase or FTX. However, through my use of Metamask I can advise that you need the correct tokens to pay the gas fee, which is the transfer fee, for the network chain that your tokens are stored on. For example, if you have CAKE in your Binance Smart Chain network within your Metamask wallet, you need BNB to pay the gas fee to transfer. Similarly, if you have CAKE in your Ethernet Mainnet network within our Metamask wallet, you need ETH to pay the gas fee to transfer. Be careful to transfer funds on the correct network chain, or you could lose it all. That is, you cannot send ETH, for example, from a wallet connected to the Binance Smart Chain network to an exchange address on the Ethernet Mainnet network. There are several bridging methods to move tokens from one network chain to another, the Polygon Bridge for example, but I have not tried any of these yet, mainly because I have not needed to. If none of the above makes sense, I suggest that you spend 100 hours watching Youtubes about the process, another 25 hours reading about it, and finally test your knowledge with very small transactions.
