Can i write my seed words wnen i offline or no need to worry ?
do not type the seed into any device. write it with a pen on paper. several times. store at different locations and NOT where your trezor is stored.
Note that the seed itself is sufficient to steal all your bitcoins. Storing it away from trezor does not help.
what i wrote was meant to prevent the situation that a fire/flood destroys a house/apartment/room - if the trezor
and the seed get destroyed there is no recovery possible.
edit: i recall a user who had placed his hw wallet on a desktop computer that cought fire. the poor guy had kept the seeds on paper on top of that same computer. all was gone.
