Everyone seems to be ignoring the fact that there is no such thing as a "scryptminer." There are graphics card yes, but no ASICS, which it sounds like you have purchased. Where did you get this from? What website? Also, I just mine coins myself going by their current value because I don't trust multicoin sites. For one they don't mine the most profitable coin because they don't mine every coin. They mine the most profitable coin from THEIR own personal list of coins, so yeah. I make a batch file for each worthy altcoin so switching take sme 5 seconds. That's just how I do it though but if you're new then perhaps a multipool is best until you get the hang of it.
That's funny, there are already asics for scrypt mining away and more coming up this year.
To the OP you will not get a ROI within 2 weeks, why 2 weeks anyway? Just mine away many different coins and exchange them for BTC, if you're smart with that many power you will definitely make some money.
