I did some calculations using https://bitcoinwisdom.com/bitcoin/calculator and found that hashie.co's (obligitory affiliate link: https://hashie.co/t?p=11245&v=3e1) miners should pay themselves off after about 150 days with a 10% increase in difficulty.

I saw a post on one of the fountains saying that microwallet.org is shutting down.  Does anybody know if that's true and what will happen to all of the faucets that use them as a micropayment system?  Move to xapo.com maybe?

Well, if it gets too high, miners drop out and the difficulty decreases and things go back to normal.

I've just started with hashie (https://hashie.co/t?p=11245&v=3e1) and the site is nicely designed and simple to use.  I asked a couple of questions to support before buying my first miner (after starting out with a free one for a day) and they were responsive.  Overall after seeing all of the other cloud miners out there hashie seemed the best to me to try out cloud mining and to do something with my bitcoins other than check the balance in my wallet or gamble them away ;-)
