there was a saying is that ,btc's price can not drop down bellow its mining cost.e.g,if btc's mining cost is 5000 $,btc cant drop bellow 5000 $,if the price is lower than 5000$ ,the mines could be paralysised ,so btc transacion cant work either.the statement sounds reasonable.to avoid this situation ,btc's price must be above its mining cost.
On other hand, the difficulty of mining btc is growing harder and harder ,if one day the mining cost goes up to the moon ,e.g, 100,000,000 $,would the price of btc also go to that level of price?but the height of price cant be maintained that high,people would of course change their btc to fiat currency,so i think its quite contradictory to ballance btc price and the mining cost.what do you think of this paradox?
The mining cost is very little to affect the bitcoin price because the more affecting the bitcoin price is the market condition of the crypto. If the market conditions more and more enthusiasts and supply a coin dwindling then the price of a coin will soar, as it is the law in the economy. However, it is fair to say that mining costs can be the benchmark for the minimal price of a crypto especially bitcoin because with the blockchain technology applied all the bitcoin transactions are processed by the miners so that if there are no miners it may not be validated. Then with that, we must know in advance how the basics of work and transaction process of a crypto with the technology.
