I think it is the crypto that he's talking about. There's an altcoin named Metal (MTL) (https://coinmarketcap.com/currencies/metal/) that we can trade on many exchanges. Well, OP, to be honest, you shouldn't just tell a short brief question without explaining what you're up to. Of course, every trade is attractive to those that are liking those cryptocurrencies that we want to trade. I'm assuming that you're asking about spot trading of MTL and it pertains to crypto since you've posted in the trading discussion and this is a bitcoin and crypto-related forum.
