A Bitcoin address is a unique key that corresponds to a potential destination for Bitcoins to be sent to. The Bitcoin address contains a string of twenty seven to thirty four, randomly generated alphanumeric characters. These strings are case sensitive and exact. They can’t be made up. Mathematical operations performed on the string create a matching public and private key required to access any Bitcoins associated with an address.
Any vulnerabilities in an actual Bitcoin 256-bit hash of an elliptic curve digital signature algorithm public key, would amount to vulnerability in Bitcoin itself.
Breaking this level of encryption requires a vast amount of processing power and requires precisely the same kind of processing power that Bitcoin mining requires. The circumstances reveal it would be especially more profitable to mine Bitcoins than to hack a Bitcoin address.
