I recently bought a Trezor so if I do start investing the majority of my coins will be in cold storage.
Great choice! While I personally prefer the Ledger Nano S, Trezors are definitely great too. Just don't do anything stupid like saving the 24-word seed on a .txt app, on your email, on your notes app, or anywhere digital, you're going to be fine. Pen and paper on a fire-proof safe will suffice. Best of luck.
