I told the haobtc CEO, who runs a cloud mining service in China, that it's users who decide Bitcoin, instead of miners.
That haobtc CEO spreads fake information such as "if hard fork happens, the longer chain is Bitcoin. And if exchanges don't recognize the shorter one as Bitcoin, they are irresponsible to customers, because shorter one is vulnerable to 51% attack."
I told him an example. If China Gov, or Jihan, or anyone has 51% hashrate. And if he creates a hardfork and the only change is to add 1M btc to his address. He uses the hashrate on his hardfork chain privately and sneakily. One day later. His hardfork chain will certainly become the longer one. Then he brings the chain back to the public.
Then according to his words, exchange shall see his hardfork chain as Bitcoin because it's longer. And if exchanges don't do so, "irresponsible to customers, because shorter one is vulnerable to 51% attack."
I told him. Bitcoin is designed to be able to win over 51% attack. If you don't know why, go to read Bitcoin White Paper. The two problems Bitcoin White Paper talks about are byzantine generals problem (double spend) and 51% attack. If you misinterpret Bitcoin White Paper intentionally, you shall be renamed as Liar Roger Ver.
haobtc CEO had nothing to say but telling me that no one can have 51% hashrate. I told him that Jihan already has and China Gov certainly has it only if they want.
haobtc CEO said: Doesn't hashrate decides Bitcoin? Any idiot doesn't think so?
Then he ended the chat.
PS: haobtc owns a pool called Bixin, which does not signal anything yet. Before cloud mining, they borrowed btc from users to buy mining rigs from Bitmain and paid back interest. Months ago, there were many rumors saying that haobtc suffered huge losses due to price soaring from $200 to $1000. But now, there is no such rumor existing.
