But instead it turned into a game of "hodl" to get rich.
Scams were openly perpetrated in the forums.
I became completely disillusioned. What exactly does bitcoin offer the world today?
for the sake of argument, is there any way to introduce monetary policy into crypto currency so as to correct for unwanted inflation/deflation? without compromising on its decentralization promise
yeah and you don't even need to change bitcoin - just use a stablecoin over-collateralized by BTC built on the bticoin network. In essence these systems work with $1 of the stablecoin backed by $N dollars (N > 1.6) of the the backing asset (BTC). Then they use a smart contract system of price oracles, liquidations & interest rate curves to balance supply, demand and risk parameters. It's pretty much an over-collateralized lending protocol that issues its own asset that is pegged to $1
This has worked well for the past 11 years with MakerDAO on Ethereum and it's stablecoin DAI. I think at its peak the DAI stablecoin had around $7 billion in circulation and was about 5-10% the size of USDT, now it's about half that. However, high treasury interest rates and low interest in decentralized stablecoins have made more "traditional" stablecoins like USDT, USDC vastly more profitable and successful. In recent times even DAI has been trying to become more like USDC and USDT with treasuries held in intermediaries
