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.
The marketcap consumed by micro-earnings or faucets which is 20% or whatever will probably add up to some other thing if people stop using them or they disappear as the demand of bitcoin is already a lot in the community and none of them are willing to choose micro-earnings to fulfill their demands.
For sure that the faucets should stop their operation, there may be a deccrease in demand of Bitcoin. I disagree that everyone should use faucet because I have never used it myself. My suggestion is every fan of bitcoin should enlighten as many people as possible that are close to them on the value of using bitcoin. By so doing will increase it demand and consequently the price too.
