The Best Miner to use right now is the Antminer L3+. It is the most powerful for its size and uses the least electricity. You can mine over 82 Lite Coins per month by setting up 4 of those miners. They have a hashing power of 504 mh/s each and only use 800w of power. Very efficient and powerful machines. Cryptocurrency mining is my latest business venture to create another income stream. Another great thing is that you do not have to pay taxes until you cash out on the coins and the miners are tax write offs.
