I have multiple trezor 1's
There is no need to won multiple Trezor One devices, and I would say it's more risky.
This is one of the oldest devices and first hardware wallet ever created, so there is a chance they are going to stop production soon.
Other Trezor models are slightly better, they have secure elements (Models 3&5) and they support more coins.
I hold btc ltc doge in them
I belong to a few exchanges to supplement my wallets
coinbase
kraken
tradeogre
I don't understand what you meant to say with this.
It sounded like you are owned by some centralized exchanges
