Too Long; Didn't Read
An annual event started on January 3rd 2019 on the 10th anniversary of Bitcoin. It was started in an effort to remind everyone that if you don’t control the keys to your Bitcoin, it’s not really yours. The most important thing that any participant gets from this day is the fact that they have (even symbolically) taken control of their own money. It reminds us that Satoshi created Bitcoin for this very purpose, to transfer value between two parties without having to ask permission or rely on anyone else.
