Added "Profitability Monitor" to auto switch between PPC, BTC, and TRC mining based on the current difficulty and Exchange rates.
http://json.karasoft.com

- Monitor works based on CGMiner API
- You can configure your Worker to Switch between 2 or 3 currencies based on Exchange rates from Btc-E as well as current difficulty.
- Worker popup window would allow you to see detailed statistics about currently configured pools and mining devices
- The following Changes can be done to you worker right from the website: Enable/Disable GPUs/PGAs, Switch between pools

I have plans to Add Scrypt based currencies during the next update.

You need to be a registered user (free to register) to use "Profitability Monitor".
