Mathematical Question [Newbie post!]

[d4rr1n]

Hello. Newbie here.

I have lurked as much as I can and tried to grasp as much as I can. Would someone be willing to explain to me what the easiest way to identify what is as close to profitable investment in terms of BTC:GH in equipment.

If not, what are the exact factors that I must consider? I am aware of the mining calculators. I just need to work out how I find out whether equipment will get near an ROI based on its current price vs the bitcoin price and future difficulty. This is something I am struggling with.

Thanks!

This is probably the best and most up to date site I have seen. Sometimes their prices can be a little old.

You must estimate how the future difficulty will change over time. It is very hard, especially if you need to wait for equipment few months... And you must be sure of unit arrival date, because any delay cost money
