BTC is glorified colored glass beads that Europeans used to buy gold from Native Americans.
and Gold itself is the same.
currency should be tied to something real, like energy. nuclear power plants should issue currency and the unit of currency should be kilowatt-hour. the power plant would be the reserve.
other units of currency could be gallon of gas, pound of sugar.
you wouldn't carry around gas canister with you but rather the currency should be issued by somebody in power to make it redeemable in that physical asset without any fractional bullshit.
Dollar is Toilet paper while BTC is a casino. Neither are money or investment.
Real currency should be tied to an asset and real investment to means of production, such as land.
