I dunno how much I am trolling here(and I didn't search the forums for a similar post), but...

ROI == Return on investment

- Is a term that implies indefinite nature, how much return do I get per X time period based upon the Y price I purchased it for. Normally expressed as a %
- (I buy shares in WizzbangCorp, they pay dividends of $1/year and their share price is $5, so my ROI is 20% per year.)

Break Even == BREAK EVEN!!!

- How long it takes to recoup your original investment. Which does relate to ROI, but it's not ROI!

-- What everyone really means when they talk about buying miner X/Y/Z and how long it takes until they Break Even.


(The aim of this post was to avoid me replying to a post that didn't have this as question (and "really trolling") and maybe mean others start to educate the rest on their misuse of terms. I can only hope.)
