Can Someone Guess My Crypto Private Key? [From Sand, to Molecules, to the Observable Universe]

Can’t someone guess my bitcoin, ether, or other crypto private key? People ask this question all the time! Maybe you’ve even asked it yourself. Most answers are something like, “No, they can’t”. But how do I know they can’t? Why is it so hard to guess a crypto private key? Watch this video where Andreas explains, in plain terms, why it’s basically impossible for someone to just guess the private key to unlock your bitcoin, ethereum, or other cryptocurrency.

Private keys that control cryptocurrencies are taken from a large number set. A really large number set. So large, in fact, that it’s almost impossible for most of us to understand how large it is. Which makes it hard for us to understand why someone can’t just guess our private key. In this edition of Down the Rabbit Hole Andreas asks himself how a human can visualize the incredible unlikeliness that someone will be able to guess your private key as he combines three of his favorite topics, cryptocurrency, physics, and astronomy! How many grains of sand are there on a beach? How about on planet Earth? How many molecules of silica in the Milky Way? How many crypto private keys are there?
