## How long would it take to hack Bitcoin?

In terms of passwords, a string of 7 random letters would take less than half a millisecond to crack. Adding a letter tales it to 5 hours and we go up exponentially from there. So essentially, the longer your password is, the better. 12 random letters would take 2 centuries to crack with today’s technology.

## How do I get a Bitcoin private key?
