Trezor wallet. How to best purchase and trade ETH with low gas fees?

Hi guys, I'm new to the sub. I am investing in DeFi and a better future with a free market actually based on supply and demand.

For reasons probably obvious to some of you I went with the coldstore open source Trezor.io wallet. I know a lot of good things are developed with Ethereum, like loopring layer 2 to reduce gas fees for example. I am just now dipping my toe in.

​

Can i benefit from Loopring layer 2, or Metamask or other stuff when using the Trezor wallet? Would i have to pay gas fees to move the funds to a hot wallet in order to trade with the lower gas fees that the "off-blockchain transactions" offers with Loopring layer 2? And would it defeat the purpose to do this as I anyway end up paying gas fees to transfer the funds before trading with them?

How do you guys using Trezor trade? Do you use Trezor mostly just to most securely store funds long term and trade with other wallets/systems that causes lower gas fees? Or do you use Trezor actively as well for trading?

TL;DR
Using Trezor wallet - how to trade with lowest possible gas fees?
