If you like BTC you have to use at least one faucet.

Imagine when all of a sudden, all of us stopped using faucets, how the market cap would shrink along with the bitcoin price? I would say, a lot. I have no specific data ( if any ) on how much cap is consumed by micro-earnings, only speculations tell me that it can be more than 20%.  
In order to keep BTC demand at current rate, any one should use some
form of micro-online-earning systems, so that faucet owners can keep buying more, resulting in steady/constant demand growth.
