Hello,
Does anyone knows how to setup good bitcoin miner rig here in my place near manila. My budget is more like PHP130k, do you think I can get 300-600 GH/s on my budget?

I suggest trying out a few of the Antminer S1's (I think you can get more than 600ghs with your budget, 4 S1's maybe)... Their prices have significantly gone down since last month... Add some more money and you can get a 1TH Antminer S2!
The only thing you need to worry about these is the power draw. Mahal ng kuryente sa Pilipinas!
Thank you sir but why prices were gone down? what happened?
Because they won't be making as much now compared to when they were released.. Bitmain also prices their units depending on the current exchange rate I think. They are priced enough to ROI in a few months. Always upgrade miners!
The S2 ($3499 i think) from what I've read has half of the power draw compared to six S1 units (which would give you the same amount of GHs)...
I suggest you use your money for group buys and hosting deals. That way you dont calculate electricity costs, and you can always sell the miner, or keep it for yourself at the end of the leasing period. Usually, by the time your lease ends (common duration is 90days), you wouldve made a little bit of profit (depending on how many shares/units/GHs you buy)...
But honestly, you really have to spend A LOT if you want to make profit off of mining. If you get cheap on mining, you wont make anything at all. My 30Gh/s USB miners which cost more than 1
BTC at the time will never ROI, so I just have it running 24/7 on Solopool.com and maybe hit the jackpot one day...
BTC price is down! Maybe you can also buy some coins, because Bitmain accepts BTC as payment, when BTC prices increase again, technically youre spending less.
