Every halving people make the same claim and every cycle we only see hashrate rising since miners are making more money than you think.
Far from the truth:https://www.youtube.com/watch?v=sw6aMxaNmXA&t=416s
I don't know if you're familiar how difficulty works but tl;dr: More network hashrate = less profit for most miners.
It's a fight for who eats most of the cake and it's getting centralized due to competition outperforming smaller miners.
Wrong. The goal of Bitcoin has always been to create a decentralized payment system.
This does not make my statement wrong, the goal was simply not achieved and postponed due to endless promises of the failed project called Lightning Network.If you want adoption to grow and Bitcoin not to be replaced by something else (and die) you should wish bitcoin remains usable. That requires low fees and no spam attacks exploiting the protocol.
So how the network suppose to survive on low-fees when there will be not enough block reward to sustain the mining operation ?
Miners are already shifting towards AI learning and replacing their ASIC machines with HPC in their facilities.
This is the biggest problem of Bitcoin - instead of fixing known issues with known solutions, people just wish everything will be alright.
