[Jan/3➞₿🔐] Not your keys, not your #Bitcoin. Today is proof-of-keys day; therefore make sure, you have full control over your coins at all times! On this day, we also want to celebrate Bitcoin's 15th birthday🎉 With the invention of Bitcoin, we were given the opportunity to own and transfer real value independently of any third party. Unconfiscatable, uncensorable & free from arbitrary devaluation. Thank you Satoshi Nakamoto🥂
