Total balance on the page:. In Bitcoin, a private key in standard format is simply a 256-bit number, between the values: 0x01 and 0xFFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 A03B BFD2 5E8C D036 4140, representing nearly the entire range of 2256-1 values. Transactions that spend coins from multiple inputs inform that the inputs may mortal a public owner) and corroborating. Improve this question.

For example, at a security level of 80 bits — meaning an attacker requires a maximum of about operations to find the private key — the size of an ECDSA private key would be 160 bits. Active keys from the output should also be loaded into your wallet or monitored for a transaction, once a transaction is in process this a positive balance, you can transfer the BTC to another address that you control.
