mining has not compensated for mining for a long time.
The average commission payment is now 1.5 bitcoins. almost half of the reward
I think you have the wrong units. The average fee is 1.5 USD.
And it will pay off only in 1.7 years
This is quite quick. Last time I looked the it was around 3 years. Most of the cost comes from buying the hardware.
Can some explain (in spoiler markdown) please?
