Did you know...that you never actually have possession of your bitcoin even if you hold your private keys in a wallet. Private keys are nothing more than an access code to a ledger account on the blockchain. A wallet is probably misleading, it is more of a key chain where you store keys to unlock and transfer bitcoin within the blockchain.

Did you know...that one of the most difficult things to produce in nature is a random number. You need random numbers to produce private keys. Stanford use a camera pointed at a lava lamp to produce data points which turn out to be great random number generators.
