What a great initiative, I like these interactive posts. I discovered POB by reading the first post of the administrator of the account @proofofbrainio, who shared his idea in the Leofinance community where I usually share my writings. Reading and understanding what it is about I was very interested in participating in this idea from the beginning, I agreed to delegate some Hive to that account to at the same time get some POB and in this way I started to share my ideas in here, with the "human BTC".
