Otherwise it won't work.
Not necessarily - They have to be paid in BTC thus causing "releasing" of coins from certain individuals (like yourself) for goods and services, and keep the BTC OR sell into the hands of wealthy USD holders buying the BTC from the Vendors/3rd Party providers and them saving.
We are in the transfer of wealth stage - but its being done quietly and off the books. We wont see increase in price unless a true ETF hits, or we get within 6-8 months of halving.
Sit back relax and enjoy the ride.
I'm generally in this camp, but I don't think many understand what's going to happen at halving, there is even a reasonable probability that Bitcoin may look dead 6 months after halving and then explode into its new price energy zone.
While I give credit to the velocity of money theory that creates value this is an end game occurrence. At the moment I think we have an equilibrium between mining investment and profit taking. If too many new coins are saved we'll see it reflected in an increase in difficulty driven by price, this could cause a rush to get into Bitcoin along with many other triggers like an ETF of some new "banking innovation"
I think the total traded coins are quite small and wealth transfer is happening but it's not a competitive environment, rather new owners are treading with caution.
