The first thing is we must understand Bitcoin is a currency as defined by the United States treasury that can be traded for or act as a substitute.

With this out of the way, let us ask a question. How many of you have worked in a grocery store? Do you remember the opening drawer or til?
Did you not have currency already in your drawer ready to give out to customers as change?
For intelligent people that answer would be yes. What happens to currency when it is spent?
Does it just magically disappear, or does it more likely circulate into the economy?
Bitcoin just like other mineable cryptocurrencies circulate into the economy through all the exchanges and through companies and individuals. No currency is just stagnant. Once any amount is sold it automatically circulates
What the reality is all the faucets that offer Bitcoin have Bitcoin in their til or wallets. All exchanges that are all over the world have Bitcoin in their til or wallets. With the amount of faucets and exchanges all over the world, including the earning platforms offering tasks as well as faucets to earn, have Bitcoin in their wallets.
The advertisement agencies paying the bitcoin to the platform to have their advertisement looked at had just transferred or purchased Bitcoin in order to have that advertisement on the site.
In other words, with all the earning platforms and exchanges carrying Bitcoin to pay their users, there is no way any one control mechanism can control or centralize bitcoin.
This is a matter of math. Remember this in closing Math will never lie, people lie.
