would it be necessary for me to buy an ASIC device in order to use it... These things are kinda costly for me.. Also could you tell me about some cheap ASIC devices... please help i really wanna be a part of this thing...
The little 333 mh/s USB asic's are cheap but an extreme longshot in solo mining low difficulty alt coins. But a dozen of them connected to a pool will get you 30 of 40 cents a month 
You have to get an antminer U3 as cheap as possible to get in the game at the bottom.
