Why would I want to use a closed source software, namely BitLocker, to encrypt a file in a closed-source OS, which could be written on paper with usage of open-source, secure alternatives?
but its still considerable if we do speak about seed or PK security.
It's obviously more secure than having your keys exposed to the public, but it is not comparably to setting up a Live OS, in an airgapped machine, and backing up your seed phrase in paper.
