[Crypto] Finding something to separate blockchains

[XMRZombie]

This issue might be important for integrating things like Stablecoins and Tokens.
Actually it's possible get the same token on different blockchains, and currently none of trading accounts or trade offers can do for example:

• $XXA (on ETH)
• $XXA (on AVAX)

[XMRZombie]

By looking in the code, we need something to inherit from multiple class (or something like that) to get multiple token formats

package haveno.asset.tokens;

import haveno.asset.Erc20Token;

public class USDCoin extends Erc20Token {

    public USDCoin() {
        super("USD Coin", "USDC");
    }
}
