this SP30 is a joke !At this price it would be good if it's delivered right now,but when this sp30 comes out in SEPTEMBER it will be useless at this price !

Yea, I want to support Spondoolie and the community and keep myself in the game, but at that current price with a $300 shipping charge the most I could ever make would maybe be $2500-$3200. So, for something that cost me $5395 and only get the most $3200 out of it doesn't seem like a good investment. And I'm working with the current numbers, the September numbers would even be worse. I'm trying to keep myself in the game, and I'd really hate to buy a few Antminer S3's, but their so damn cheap it is hard to say no. I'd rather use a Spondoolie product for good support and a quality product but maybe this go around I'll just stick to buying bitcoin out right from now on and not have to worry about hardware. Apparently it seems everyone in the world is putting up their own data center these days. In my opinion, the main problem and concern we ALL should be worried about is power.

Opentoe, please do me the favor of replying to my question with your (approximate) percentage gains from your calculations. Just curious.

Obviously I used an online calculator and it came to about %66. I used the Tradeblock site, which isn't set in stone with the output numbers, but I would definitely say they are a good approximate. Here is what I input for one SP30 starting in September.

Maximum profit only indicates $3630, and yea, I was high with the difficulty increase cause I'd rather have worse case numbers to make a decision on. I think if I spend over $5k on a mining rig and then have to spend $300/month to co-locate I'd want a better reward than $3k-$4k. For 6TH/s in September I think $5395 is too much right now, that's all. I'm hoping all the numbers are correct. The reason I kept the diff at 20 is because at that time there will probably be a slew of KNC Neptunes online, thousands of Antminer S3's and, another one called Rockminer?, and then of course Spondoolie's. That's a huge dent onto the network, and if you adjust that difficulty setting on that page it does change your max profit considerably. The lowest change in 4 months has been %10.66.

I've never been a risky person, so I hesitate, and sometimes I lose out. The best thing I ever did was buy a KNC Saturn and then bought 4 upgrade modules. That little guy is still chugging along. I think if my house had more electrical resources and didn't have to worry about cooling I'd have mining rigs all over the place. It is addicting.

whatever you linked to on traderblock assumes 20% increase in a MONTH, not a cycle.
20% is definitely on a lower side, but possible in 6mo
I would use 30%/mo. In this case-about breakeven in april 15.
here is is:

bottom line: profit is possible ONLY if difficulty stagnates to below 30%/mo AND bitcoin increases in price.
