The only alternative currency that wouldn't burn energy would be shares in transferable energy itself. This would require a global energy grid which we don't have, and are not intelligent enough to seek to develop. Once such a grid exists, then shares in transferable energy would have a relatively stable value.
Work is energy.
Money is proof of energy.
Money is bitcoin.
Where am I wrong?
You buy bitcoin at the price you deserve.
Bitcoin is inheritly more equal than fiat because the cost of issuance is the same for everyone i.e. you don't have a select group of people who can legally counterfeit it and accrue enough power to effectively control the world.
If anything risk/reward ratio is a better proposition than it was then - we have 15 years of solid operation, nation state adoption, ETFs and far less volatility yet the upside is still enormous.
You can buy "risky" bitcoin now at $50K, or you can wait until $50M when everyone and his dog is using it to store their wealth. The choice is yours.
