I am currently planning to mining BTC using Antminer S9 (14 Th/S, 1400 watt, price Rs. 2,25,000/-  Electricity rate 0.1 USD/Kwh)

I browse net for some BTC calculator which consider difficulty increase rate as well as network hash rate increase rate.

Some of them saying that i will never get ROI or some of them showing that ROI will be after 5 years.

What is true?

Is it worth to mine with miner or just buying and hold it.

Note: i am not comparing price of the BTC. I am just comparing that at the current rate of 6000 USD/BTC and 65 INR/USD i will get 0.577 BTC, then how much time it will take to generate that much BTC with miner.


Thanks in advance for your help
