Hello guys, has it ever happened that some pool had exceeded 51% of Bitcoin hash-rate? I tried to find some information on the Internet, but there are many articles which are not in the contrast so I am not able to find out which of them are correct and which are just hoaxes. Thank you
I don't think it's possible now. I mean, there is one company that dominates the market, but to get 51% it still needs some consolidation if I remember correctly. Moreover, it's something that will ruin the company's business and reputation, so fortunately it's very unlikely to happen. Profits drove the companies, and losing everything is not in their interests. It seems that this has never happened, though, and would not destroy something as big as bitcoin right away anyway.
