you first need to distinguish coins from tokens. Coins ^{especially Bitcoin} they have their own network, blockchain. so don't even look at him for it.

Check here, when you follow this fantom:



When you click on three dots in contract info, you get a complete list of which networks you can use to transfer that coin. Each network has a separate address for it so that the transaction is not lost between different types of networks.
It's not possible to send fantom ^{or any other token} through the Ethereum network (as ERC20) to Binance smart chain (BEP-20). I mean, you can send it, but they will not reach where you sent them.
there are no differences in the token itself, but only the difference in the network you use for transactions. it is very important that you understand this and always be careful when sending/receiving.
