Talking about miners selling their their Bitcoin, in every business organization, there are different strategies from different people.
They do sell their Bitcoin for reasons best known to them. In the digital marketing, people's aims and target are mean to be met before restiveness but one thing for sure is that before they sell their Bitcoin maybe they have enough in their Blockchain and will like to be as a result of rising issues maybe the cost of generating electricity because mining meet a standard supply of electrical power.
Miners strategies are different, sometimes they fear the collapse of stock price like in some years miners do hold their coin for a long period of time or years so that it may yield a profitable amount but also having the fear of the market fluctuating inflation..
Bitcoin mining is of patience and needed time as well as a busy day and after all these, the companies have the opportunity to allow all miners earned a profitable amount but they are unlikely.
The fear of most companies being fake or unreal can make every miner with some coins sold at a price. Besides every miner have the right to sell their Bitcoin at any time for their own benefits because it is a business which they run every day, it is only for the beginners to doubt out of their novicism.
I want to point out that every miner has a cost of mining Bitcoin, and statistically, with the average
price at $85,000, miners are reluctant to sell coins for $100,000. Miners are waiting for a better price, but the sudden price drop from $120,000 to $60,000 was difficult for everyone in the crypto world.
