I know Tails have Electrum added as default, but is there any other Operating system with a default wallet added to the software? There are
so many Linux based implementations, but none of them seem to have a default crypto currency wallet built in by default.
Knoppix has it too. Both are LIVE CDs, they're meant to be complete and ready to use.
Most Linux distributions have several wallets in their software repository, I installed Bitcoin Core with just a few clicks.
Should we not approach these developers and ask if this can be added as a default option?
No. It has enough pre-installed software that I never use. That's what package managers are for.
