Okay thankyou for that information..
one more thing.. is that.. if i invest in cloudmining.website or similar.. cloud mining .. will that be profitable ? according to their calculations they say ROI will be around 5 months..
A lot of the mining calculators are way out as they do not factor in diff increases. With cloudmining.website looks a very low budge site and looks to me wouldn't make any return after reading in
https://bitcointalk.org/index.php?topic=843417.0 lot of people and some are saying doing their own calculation on cost of contracts to RIO would be more to 4 years before broke even.
This is taken from info on someone else details
Total invested = 0.13 BTC
Total received = 0.19206015 BTC
Profit made so far = 0.06206015 BTC, i.e. ~50% profit made in one year
So for them to say 5 months their calculator is way out and not correct. I would just buy Bitcoin hold it and wait for rise sell it get your profit that way then buy back in low and repeat the cycle or learn how to trade online and make far better results than any mining contract can provide.
