Future of Bitcoin Economics depends on mass adoption of Bitcoin. No body can predict accurately the true future of Bitcoin.
Just as important, IMO, is "
merchant acceptance" of Bitcoin. BTC truly needs more goods & services providers who will take BTC as payment. Some already do, but not nearly enough.
If Bitcoin price keeps going up, that will attract attention of BTC buyers, and with luck more merchants will then opt to accept it.This won't work the way you think it will. Why? Because Bitcoin supply is limited, so the quantity of bitcoins available for purchase eventually diminishes. More buyers pursuing less coins leads to price increase until one of the
new whales (born due to the price increase) decides to cash out, and then the price quickly spirals down. That is good for speculation and profiteering (and wealth redistribution, to a degree), but not for Bitcoin acceptance by the suppliers of goods and services. Merchants are not so much interested in Bitcoin price (high or low) as they are interested in the price stability...
Which is impossible to reach given the Bitcoin price dynamics and the mechanics of such dynamics
