The upcoming Halving Bitcoin will double the cost of mining, causing the price to skyrocket to $ 90,000 or higher
A mere newbie saying this kind of stupid nonsense things here 
. Good Job dude.Any evidences that this will happen?? If you can defend what you said then I will believe you. The true and might happen is that, most of the miners after Bitcoin halving might stop mining because of the reduced income by half. Probably those who are living in the countries where the electricity bill is low are the ones who will not stop. If the miners see that they aren't profiting after halving, they will stop. Simple as that. Bitcoin to $90,000?? Possible but very low chances (around 0-1% TBH).
I agree. I don't see any incentive for miners whose production(operational) cost is not covered by the market price. I mean they could be more profitable by just buying bitcoin on spot and only plug their gear in when they should be profitable or even sell their rigs to fiable companies in other countries, but then we'll have a centralization problem..
