In the grand scheme of things
1 #sat = .1 miligram of gold ( around 2034 )
1 bitcoin = 10 kilos of gold
Cuz
21 million btc = 210 million kilos of gold ( the final supply threshold )
A #goldback is still delaing with ounces .. which doesn't fit well into global metric system..
Besides ..neither sats nor goldback will ever be used as a currency .. they are the apex assets ..
