How many miners do you think was mining Bitcoin core back in 2009? And you're not concerned that the major Bitcoin Core miner - Blockstream is owned by Axo group who's CEO is a Bilderberger chairman? I believe that is more concerning than a coin being run by an anarcho capitalist (Roger Ver)

Also, BCH has 4 different developer teams, and the miners that mine are the same that mine BTC. I don't understand what makes BCH so much less decentralized?

If you look at the last 1000 blocks mined and 400 blocks mined, you can see that it's evening out very fast.

Oh, and don't forget..unless you sold your BCH you're invested in BCH as well :)
