I'm starting to experiment with Bit Blocks -
https://bitblocksproject.com/It's very low value, and low volume at the moment, but I'm hoping it will pick up over the next months. It has a faucet at the moment, and I'm using that to collect a few coins to build the asset base for the crypto coin tree. The faucet only pays between 0.5 and 3 coins per claim, and the current value of these is just a fraction of a penny. The use of the faucet does give an idea of the speed ans convenience of the system, so you are welcome to claim using our donation address - BDmzTdZ41ZRdostLt1vkf69x7nyXujQYV3
The faucet can be found at this address -
