I was worried about that, I see an article before the halving event happeened who stated that the miner will be profitable if bitcoin price has a price around $10.000 when halving event has happened. So I just thinking that in this situation there will be some miner who leave their mining rig until the price of bitcoin back to high. They are an important part in bitcoin ecosystem because they have a function to validate every transaction but they will thinking to pay each cost if they turn on the mining rig to start mining bitcoin. Hopefully bitcoin price will increase again and reach new all time high.
