I'm being a hard time finding what is the meaning of Poc, some said it's Proof-of-Coin, some said it proof-of-concept
but what is the true meaning of PoC at the current moment when all of the BTC and Alt are green and they say 99% are just PoC?
PoC stands for Proof-of-capacity and It is the ability to utilize an empty space in your hard drive to mine free coins. Proof-of-work (PoW) and Proof-of-stake (PoS) are the most common ones most coin uses. There is only one coin that uses PoC, it called Burstcoin.
