If you are switching to this because mining for Bitcoin is unprofitable, then you are only fooling yourself.

Scenario 1)
- You give $100 to the goat-needing families

Scenario 2)
- You mine 5 BTC for Coinbase, using $100 of electricity.
- Coinbase converts the BTC to USD.
- Coinbase sends $67.50 to the goat-needing families.

And no one sees the problem with this?

Now, if mining is still profitable for you, then all power to ya!  Just don't fool yourselves by thinking that this is a good idea if you can't already make money Bitcoin mining.

Also, Coinlab hasn't mentioned if 100% of the proceeds are indeed going to these needy families, or if they are taking a cut for "server" usage or something.  Would be nice if they put what percentage that cut is up front.
