Why is more layers and more fees always the answer with these clowns?
Because they are programmers and nobody's telling them what to do.
They're fitting the problem to the solution and making a complete pigs ear of it. Your Euros not fungible enough ?...here have some Escudos instead but we need to confiscate your Euros in the meantime - don't worry you can get them back when your finished. Waiting to long for your transfer ?...here, I'll convert your Rubbles to Yuan which is instantateous. (Oops - you'll have to wait for them to 'cook' to the right level of security, but you can BUY some immediately in the swap market at a premium !)
Thats not a currency, thats an economy. Only worse - because they're all mechanically pegged to each other so that any volatility in one sector gets transmitted all over the place to sectors that would be otherwise stable in a genuine, economically diverse currency market.
Decentralised market logic: "Volatility is a required response to out-of-balance distribution of a market commodity/asset which forces it back into equilibrium"
Clown programmer logic: "Volatility is bad. It's caused by scam pumpers and dumpers. Solve it with programming so that the volatility gets re-distributed instead of the market commodity/asset"
