PoC stands for Proof of Capacity.
You can find more information about it here:
https://www.investopedia.com/terms/p/proof-capacity-cryptocurrency.aspThe internet contains loads of information, try using it.
at the current moment when all of the BTC and Alt are green and they say 99% are just PoC?
I don't see any relationship between the current market and the PoC algorithm.
Bitcoin uses PoW, which is Proof of Work. And other blockchains uses different algorithms too.
