How many bitcoins must be sold to get more benefits? At least a gain of at least 550 million is needed to balance the balance on the book, but such a big attack is to be done, and the currency value after the attack will drop a lot, so a very large benefit is necessary for the attacker to do this. We estimate that we can make a profit of 2 billion from selling Bitcoin.
Bitcoin holdings = 2 billion / 4000 = 500,000 Bitcoins
We assume that the attacker owns Bitcoin at a cost of 1,000 yuan, and his original purchase cost is 250 million yuan.
If you sell 500,000 bitcoins in a short time, the price will hit the bottom of 1K-2K from 4K.
Let's just assume that this is an over-the-counter transaction and has no effect on the price of Bitcoin.
- The value of Bitcoin after a successful 51% attack
After the successful implementation of the 51% attack, we believe that in a long period of time, people’s confidence in Bitcoin will drop to the freezing point, and the price of Bitcoin will be at a lower level, such as 500 yuan or even lower, until the technology solves the problem forever. % Probability of attack.
Therefore, even if the attacker successfully implements the attack, the value of his 500,000 bitcoins will be at a low level = 500,000 * 500 = 250 million.
