Hi All,

I just tried this yesterday and it worked: http://aws.amazon.com/big-data/powerof60/
You will get an e-mail within 5 minutes with the Redemption code for Amazon ews $100 credits.

You can use it for example for about 19 hours of 20 cc2.8xlarge servers mining Photoshares (PTS)
Current Spot Price in Oregon for cc2.8xlarge which is a 32 core box is @ 0.253 / hour
Spot Price in Virginia for cc2.8xlarge is @ 0.27/hour

Here's how to quickly mine some photoshares:

1. Create a Spot Request for Amazon Linux AMI (HVM) 2013.09.1, select Compute Optimized cc2.8xlarge instance.
Put in your maximum price of 0.253. (Don't put in more than the current spot price, as you will automatically raise the price for the next time you want to
create a spot request/ or someone else )
I like to check the Persistent Request box so that it will try again periodically if it's not able to fullfill your request.

2. After you request get's fullfilled( usually within 5 minutes) connect to your server:
  
3. Now, let's set up Photoshares with yPool:
You have to get the latest linux miner from yvg1900 from https://mega.co.nz/#F!h0tkXSxZ!f62uoUXogkxQmP2xO8Ib-g
You should get core2 version: jhprotominer-yvg1900-M7ff-linux64-core2.tgz
I uploaded it to my dropbox and copied it from there, but if you are paranoid, you can do it yourself

Next, we need to extract it:

Now, let's cd into (cc2.x8large box has 60 GB of ram, with 32 cores, enough for 1GB of ram per mining thread...

You can then run the miner:

4. Make miner start after reboot...

Add the following line to crontab:

Save the file with ":x" and you are set.

5. Now the easy part: create an image of your running instance: select instance -> Actions -> Create Image
6. After AMI is created, you can pick it when you make Spot Requests.
7. Spawn 19 more instances and watch your yPool shares go nuts...
8. Turn off your servers in about 19 hours...

Hope this works for you.

If it does, please drop me some BTC @ 1GU6NwUU5tS8doqfwgEfZR4mfTU7fqo4XF

我的观点是：
看你自身特点，如果是程序员IT业的技术流，那么去挖矿；如果是玩股票金融圈的，那么去炒币。
无论哪一边，要玩深都有得玩！我自己是偏技术流的，也在挖矿，如果细细去折腾是有可能达到高于100%收益的（p2pool矿池慢慢调，当然调不好也可能只有50%收益）。
如果两边都靠不上的话，减少你的入场本金（其实2W也不多……），抱着玩玩的心态，随便选一个。

话说到底，就是看你自己的能力和技术更适合玩哪边。

个人建议，供你参考。

买个2w 矿机好，还是买 4个币囤着好？ 买矿机的好处是干多拿多，但是什么时候能回本，一天平均能静赚200~300人民币（扣去电费）不？ 囤币好处啥也不用干，但涨跌就看老天了。
