trezor – What’s the Most Frictionless Method to Get Bitcoins into My Pockets?

Whole noob in crypto (purchased my first few mBTCs a month again) and a proud proprietor of a brand new trezor one {hardware} pockets.
I wish to ask what’s probably the most direct/frictionless solution to get the bitcoins into my pockets?

I’ve already arrange my pockets and did my first switch into it, it labored. However I needed to first enroll and purchase the cash through impartial reserve, after which switch it to my pockets tackle. The impartial reserve charged me once I paid my {dollars} into their account (paid $500, they credited one thing like $497), then they charged me a number of satoshis once I transferred from that change to my trezor. Appears very convoluted.

Is there a extra direct approach, with out going by these additional transfers?

Associated, the trezor one suite (I’m utilizing the Linux Deb model) has an tackle in it, together with a QR code. Is it protected to make a copy of this QR code on my cellphone, and flash it at a bitcoin ATM (or share it through whatsapp to any sender) to obtain Bitcoin? Will the ATM ship it on to my trezor one?

Sorry for the noob questions, simply attempting to determine the most secure and most value efficient methods to navigate the panorama.
