Future of Bitcoin Economics depends on mass adoption of Bitcoin. No body can predict accurately the true future of Bitcoin.
Still much more predictable than the future of fiat currency, which doesn't look good, BTW.
At least with Bitcoin you know how many coins will ever exist, whereas in the case of fiat, governments can print money at any time.
Fiat currecy just a tool by the goverment to control the financial and economic sector. About the future of the fiat that can't be determined caused by the fiat depends on the goverment itself.
The government has used the polics issue to manipulation the fiat money, the government can print it anytime.
Bitcoin was very different with the fiat money.
