Why Is a 51% Attack More Difficult to Execute on a Large, Established Network like Bitcoin?
A 51% attack on Bitcoin is prohibitively difficult due to the sheer scale of the network's total hash rate. Amassing 51% of the global hash power would require an astronomical capital investment in ASICs and an ongoing, massive operational cost for electricity.
The financial cost of acquiring and maintaining the necessary hardware and power far exceeds the potential gain from the attack, making it economically irrational.
