I had been very much disturbed by reading articles that criticize bitcoin for using excessive enerfor mining.Nowadays such articles could be seen in large numbers.But the reality is different.Its just a false allegation against bitcoin by the biased media which is mostly funded by corporates.For them,those media deliberately spread FUD against bitcoin mining.
But bitcoin mining is using much less energy when compared to energy used for gold mining or bank transactions.
Such articles directly equate the number of transactions directly with the mining cost.But there is no such thing.The cost of mining stays the same both when a bitcoin block is full or empty.
