Just a quick note for all of you doing various ROI and profit calculations - all calculations that I've seen are made on the basis of ZenPool's profitability. You should be very careful with this. ZenPool has a ?magic? profitability - 50% higher than any other well established multipool.

This kind of profitability is simply unrealistic. I'm not saying that it is impossible - but take into account this:
- what kind of a magician one must be to get 50% higher profitability comparing to all other pools where all multipool operators with years of experience can't find such a magical key?
- to make this kind of profitability with nearly 200 GH/s hashing power one would instantly kill any altcoin that might be so profitable in a specific period of time.

That said - ZenPool's profits are likely unrealistic and are probably paying additional profits from their own funds to provide this kind of profitability (similar to Ghash.io promotion a couple of months ago) - I guess this couldn't last forever (or even months).

So I advice all of you to calculate your ROI's based Litecoin profitability instead of ZenPool's profitability - otherwise you are most likely gambling. Of course, you can never know, maybe they actually did find a magic wand for the ZenPool? Believe it if you want (or if you can afford to believe)
