A tool to split your wallet in two so that each half can be backed up to different cloud servers but neither half can be used to spend your coins...
you can compress and split with rar files just tried no unrar without both halves
Would you bet BTC500 it's secure? BTC100,000?
If you're really offering a bet, I'd be very willing to take it. It's a very simple, but functional solution.
I'm not offering a bet...I'm asking would you run this process on your wallet worth up to a million bucks and send someone 1/2 of the RAR file set? I don't know the details of RAR well enough other than the program doesn't do anything unless you have the whole set.
