Hey guys, I've been a long time lurker and I finally registered to post about MiningUnited.com
This is a website for renting a mining rig for short term gain. You get a set amount of bitcoins depending on the package you "purchase".
I've been using them for about 3 weeks now, and have gotten paid out multiple times. Most miners can make more mining on their own, with their own hardware, but this is a way to supplement your current mining income. I'm mining on my rig, and sending bitcoins to MiningUnited.com to make extra bitcoins. They seem to make their money off of Premium membership fees.
The current price structure for mining packages are:
0.05 for 3 days of mining will get you: 0.0662 back
0.10 for 3 days of mining will get you: 0.1339 back
0.25 for 4 days of mining will get you: 0.3517 back
I would suggest you check them out. (I do not own, run, or sponsor this website, just passing along information.)
