The current blockchain is only slightly less centralized
Apart from that, most people basically don't care whether Bitcoin is centralized or not. All they care for are profits and nothing else but profits. If Jihan in some ingenious way makes them choose between losing the value of the coins on the "regular" blockchain and acquiring that value on his blockchain, they won't think twice (you can be dead sure of that). Further, what makes you think, first, that Jihan and his goons (who are collectively known as the mining cartel) have less coins than some obscure "whales", and, second, that some of these whales (say, Roger Ver) won't in fact prefer JihanCoin?
the current state of centralisation is kind of the elephant in the room. if it breaks out and starts smashing things like a bitmain controlled coin would i think enough people would start to object.
right now it's just about bearable enough but it's kind of a fragile precipice.
yeah, i think enough people would be lured by the money to stick around, but it would only take one demonstration of their power to make things falter.
crypto has got to have something to look to when it comes to its principles. bitcoin is it.
