I've been seeing so many debates about a 51% attack as well as its costs and everything else. Now, I'd like to ask this whether it should be considered a crime that is done to potentially harm / kill the network as well as destroy BTC? Can somebody, after attacking BTC, mine all the BTC in an hour or so? Can everyone become helpless to just stop their mining operations completely whenever such a situation arise? What if the attacker decides to pull out USDT against BTC and sends his coins to an exchange? Will the exchange accept the coins? Can he even make nay money by conducting such a highly expensive operation? Will somebody be even interested in making money from this or the sole intention would just be the destruction of BTC as well as the network, and to gain Monopoly and establish the rules of centralization in crypto world?
