@OP, next time you use PoC, state what it means. There are other projects that uses it but they have different meanings (Proof of Concept, Proof of Care, etc).
Now, the project that you are asking (most likely shilling) refer to PoC as Proof of Capacity. They aim to make mining much easier, cheaper and more accessible to ordinary crypto enthusiasts but will that be enough to dominate the next bull market as they say? I have doubts but we will have to wait and see. I wouldn't risk investing in such project until they've proven themselves with their real products. Many have tried to compete with POW but none have come close until today and I don't see that changing in the near future.
I have seen many project which prices increase hundreds of times....I think it is interesting to invest some, maybe with not too much money
