Reddit netizen Illsellyoullbuy recently posted that his/her computer engineer friend has a lot of research on the blockchain industry. The engineer claims that bitcoin mining is 11 years later (2030) due to continuous reward halving and high electricity bills. It will stop because the cost is too high. The miners will have to give up mining, and without the miners, the new bitcoins will not be excavated. This post sparked a heated discussion in the forum, and the encryption community was skeptical about this. It has been suggested that new technologies will continue to develop and will provide renewable energy to more and more people, and the future electricity price will inevitably decline.
