bitcoin private key length, The Math Behind the Bitcoin Protocol

In the world of Bitcoin, bitcoin addresses (in a format similar to this: 1JwSubhmg6iPtRjtyqhUYH7bZg3Lfy1T) are equivalent to bank accounts, and Bitcoin private keys (in a format similar to this: 5KJvsng) HeMpm884wtkJNzQGaCErckhHJBGFsvd3VyK5qMZXj3hS) is equivalent to the password to open this account, an address (account number) corresponding to a private key (password). Only know the Bitcoin address can not know the bitcoin private key, but also can not use the bitcoin inside, this is the same as you know someone else's bank account number but do not know someone else's account password can not withdraw money and transfer. But what is different from a bank is that knowing the bitcoin private key can tell its Bitcoin address and can transfer bitcoins under that address, which means that obtaining the bitcoin private key has full control of the private key and bitcoin under the address - the private key is everything! So if 1: You lose your Bitcoin private key, or 2: Your Bitcoin private key is known to others, the bitcoin under your address is over: either you will never be able to use the bitcoin on the address or you will be transferred by someone who knows your private key.
