Bitcoin is not decentralized. It was designed to be decentralized at first but ASICS companies destroyed the idea. Satoshi wanted everybody with a PC to contribute to the POW system but after ASICS miners came, it became big companies' business. And there isn't even a competition left now. Bitmain killed every other company out there. So how is it decentralized?
You'll understand this when Wu's miners gang support of BU becomes >%50. Our only hope is the community now. If they choose the easy way and go after Wu, bitcoin will be another centralized piece of shit paypal copy.
since u mentioned Wu, some say he should be put in jail. He is been suspected of blocking segwit on purpose.
