Proof Of Keys
Every January 3rd, those who HODL bitcoin are encouraged to participate in an initiative started by Trace Mayer, wherein they withdraw any and all of their bitcoin from exchanges, and third-party custodians. This #ProofOfKeys celebration is aimed at furthering the cause of monetary sovereignty, by everyone to control their own private keys.
