Well, Im very new in this whole BitCoin mining stuff but i need to know where to start.

I see all of these RedFury and Blue Fury (Sapphire) USB Block eruptors and was looking to buy a couple and even some other ones.

Hashing around 3.2 Gh/s

If it smart to buy these to start everything off? I am more than likely mine Altcoins first.

I just dont know what to do help!!
