There's a private key found on the internets to a wallet that was supposedly Satoshi's 50 btc.
I guess somebody cracked it somehow, got the fifty and let people know the private afterwards.
When I enter that private key to my Electrum wallet I see nothing.
There's no history even though you can see its transactions on blockchain.
Looks like Electrum deliberately blocking this particular key. Why?
