user61417: I am considering buying a trezor wallet. I am wondering if this type of wallet can support all types of crypto currencies? 

user38618: See "Which coins are currently supported?" on Trezor FAQ

At this moment it is Bitcoin, Ethereum (+ all ERC-20 tokens), Ethereum Classic, ZCash, Litecoin, Namecoin, Dogecoin, Dash and Bitcoin Testnet

So the conclusion is, Trezor supports most of the altcoins, but the computer software doesn't. If you can't code a software that allows Trezor to hold more altcoins, you can only use the altcoins in the list, with the name of the wallet next to it.
