Petro-yuan: China wants to dethrone dollar

Not sure but I guess it is about what it can buy. For the average user, what does a tanking US dollar do? Gaddhafi was going to dethrone the US dollar control on oil too by using a gold backed currency, they killed him.
The future is one where the USD is not the default world currency. So it seems crazy to tether a crypto to a currency that is on a descent. The whole point of crypto was to replace the old system of money, not support it.
