Like tone vays on ethereum bitcoin mining market share major currencies such as gold, United States dollar, euro, yen. Won't Bitcoin fall in a deflationary spiral? However, there is a delay before the network begins to confirm your transaction by including it in a block.

This requires miners to perform these calculations before their blocks are accepted by the network and before they are rewarded. Large coins such as Bitcoin are not afraid of a 51 percent attack because every attacker with the vast majority of hash power would have been more motivated to mine all the blocks and get Bitcoin instead of trying to attack, especially given the price of their stolen. Can Blockchain be Hacked? Such proofs are very hard to generate because there is no way to create them other than by trying billions of calculations per second. Bitcoin miners perform this work because they can earn transaction fees paid by users for faster transaction processing, and newly created bitcoins issued into existence according to a fixed formula. The rules of the protocol and the cryptography used for Bitcoin are still working years after its inception, which is a good indication that the concept is well designed.
