what cryptos does trezor support? do they have wallets for many cryptos like ledger?
Trezor supports quite a lot, though not as many as Ledger. The Trezor wallet has a coin-selector menu which lets you switch between supported coins. It\’s kind of similar to how Ledger does things, I guess, although you don\’t load a separate wallet interface for different cryptos.
Here\’s the full list of coins they support (and through what means) as of the 6th of December 2017:
Bitcoin Cash / Bcash
Custom TREZOR Wallet
