If faucets are what it takes for BTC to survive, thrive and go mainstream that is all the reason one would need to dump their holdings and forget about BTC.
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.
