RE: Bitcoin mining step by step - Profitability calculation

in #bitcoin8 years ago

True, I've tried to make this sum profitable many times but if you don't actually get electricity for almost free it just doesn't seem worth it. Not to mention the time waiting for your equipment to land and time is definitely money in this equation.

Sort:  

What miner tool can you recommend and how long is its ROI?

@juvyjabian, I do not suggest you to try mining. As I show you in the article it is not profitable at all. You will not do any money doing mining.
For Antminer S9 at current prices of bitcoin you will never a positive income.
If you can invest 1-2 million dollars you could find a way!

Oh too bad. Im planning to buy 5 S3 at the end of the year which according to the seller, its ROI is 1 yr. You mean its not true?

You are going to buy 5 S3 from BITMAIN or second hand?
The profitability depends mainly on the sell price, if you provide me the price I can quickly check for you...

Its a second hand actually, less than a thousand dollar.
