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
For PoW, where miners have a very high grade of long term investments like in asics and plants, contracts, datacenters, leased lines.... any attack doesn't make much sense.
Open competition is much more important cause that will allow any sort of innovation and change & break any bigger players in the long.
Any attack is lowering price and reputation. What long term Investor would like to risk such ever?
