hey,
I wonder, even if the probability so small is, if someone else get the same private key as me could he/she spend my Bitcoins and viceversa? would we have the same Bitcoin Adress?
of course, this is the importance for us to keep private keys from people who can not be trusted because it leaks once our assets can be directly spent or transferred to their personal wallets and none of them can help because of the decentralized nature of bitcoin.
