I received my Trezor 3 Safe today and on set up i can only see say 8 coins that i can send to the hardware device. I thought there were thousands ???
There are several types of supported coins in Trezor devices. Some of them are natively supported in Trezor Suite, and some of them are not. For those, you need to use compatible 3rd party wallets. You can find more information in this video: https://www.youtube.com/watch?v=w-3XRO5u8kc&t=1s
If you want, you can let us know the coins that you are interested in and I will provide you with further information about these coins.
