I was taught that if I was holding my keys on a Trezor /Jade /Cold Card /etc and that if the company went under and didn’t exist anymore and if I lost my device or it broke or w/e I would still be able to recover my ₿ on another wallett as long as I had my private keys . So if Trezor ( I plan on getting a ₿ only device very very soon ) was to go out of business and I wasn't able to get a new Trezor how would I go about recovering my funds ? I have a 4 digit pin set up on my trezor as well . I have already made the mistake of putting my private keys on Blu on my mobile yesterday when my trezor broke and will be moving the vaste majority of those funds to a new wallett as soon as my new Trezor is here tomorrow.
