OP sees green dollar signs dancing in front of his eyes when he read about bitcoin mining. Human greed knows no bounds. Greedy idiots abound in the forum. LOL
Here let me help you part your money:
Bitmain S7 Batch 10, about 2.1 btc plus shipping and custom fees
Avalon A6, about $1150 plus shipping
Since you're a small fish, this is the best miners you can buy at this time. Please hurry spending your money, mining becomes more and more "difficult" as time goes on, the sooner you buy the miners, the more you make. Some people have made so much money mining, they bought Tesla and big houses. LOL
A6's are actually around 9000 for 10 currently on BlockC. So they did go down a tad a bit ago.
The difficulty is hurting though on all miners. Just hard to keep up it's getting insane right now.
