Make sure on your miners to add difficulty change in ROI math. Calculator posted before in thread is great for 2 periods, but with miners you will mine most likely a lot more time then 2 periods. Try the one here - https://bitcoinwisdom.com/bitcoin/calculator
What is your electricity cost? This is one of the very important calculations which let us know if mining is for you.
Also on cloud mining make sure to do research. Sadly a lot of bad apples out there. Anyplace that guarantees ROI or profit on cloud mining is a scam. Just like regular mining cloud mining can ROI or could not. But do research on the site before investing. Which you really should do on any investment.
Very good information thanks a lot man
