This seems to be a hot topic lately and I am seeing it everywhere. People are assuming that mining cost is related to Bitcoin price but that is not true. Basically the hashrate is mostly followed by price. When the price goes up, so does the hashrate. However the opposite is not true. When price goes down the hashrate can either go down, stay the same or even go up. Usually when price goes down the hashrate stays the same or it goes up. So obviously mining becomes unprofitable for some, they just stop mining and move on. The price will not jump so that mining is profitable for mining farms, doesn't make sense.

Price had a huge surge by around $1000 or so because it landed on previous support and there were too many people short. The funding rate was very negative on Bitmex and obviously there would be some type of short covering rally which is what we saw. People either shorted the bottom or they shorted before the drop and their trailing stops hit. That's why the rebound was so huge and now we are trading sideways until the market decides which route to take.

when prices go down I'm sure there will be a rebound in prices, because when bitcoin reaches their support people will automatically buy it and create price reflections. and I think the price reflection some time ago provided quite a lot of advantages especially for those who took place at that time

There is no relationship here. All I see is your conjecture. The average cost of mining is only part of the value of bitcoin. A small factor cannot make a big impact. Do you understand that? The average cost will be adjusted by the price of bitcoin, because when the price of bitcoin is low, in the event that it does not generate profits for miners, the miners will leave, and the cost drops. Or high bitcoin prices, many people will mine bitcoin, which means that the average spend increased. Or to be precise, the cost does not determine the value of bitcoin; on the contrary, the value of bitcoin determines the cost.

what is sudden when Bitcoin price Bounced back?lol this is something to be thankful and not a sudden situation (not unless you are anti bitcoin)
soaring high in the beginning of the year?but remember Ethereum Grows high last january 2018 .

but yeah 2020 is expecting to bring fortune to all of the holders and miners so lets see what will happen in the 3rd quarter of next year because the effect will take place before end of year.

I think what most people believe is that it is all tied up, but no concrete evidence is to be found. They believe that hash rates correlates to the price of Bitcoin, and also hash rates is connected with the cost of mining, in which also is connected with the current price. Still, there are no studies to be found that proves such theoretical statement. There are still a lot of factors, the market is volatile and whales could manipulate any time they wish.

Not a strong reason but actually does make sense, it could somehow change the perspective of people regarding bitcoin which is "Created out of thin air" while actually it's being mined that takes that much money to generate. Though, the difficulty is too high as of now but it'll be no problem if the mining rigs out there are powered with renewable energy. Other than that, there's no real correlation regarding the sudden price spike with this news.

The reason behind Bitcoin's price changes is undefined and we can't figure the exact reason out. There will always be conclusions and speculations but that's part of its volatility. Every event has an impact on its price and it can be a positive or negative effect. There will surely be more events that would influence its price soon.

We have had many rebounds and they all failed miserably, especially the one where the price pumped from $7.3k to over $10k. If you fall below $7.3k after such a bullish move, that's ultra bearish. There is no way to describe it differently.

Do I think that we have had the worst of the selling? I believe so, but that doesn't mean that we can't drop further. We haven't yet seen a capitulation candle that generally gets most of the weak hands shaken out similar to the one of last year.

There is no relation of mining Bitcoin with the price of Bitcoin. Panic sellers caused the market to go below $7k, which was an opportunity for the whales.

They bought it and hence you can now see the price above $7k.
