It is very simple.
What you have does not change in proportion to the total. If you have 1btc or 1.000 millibtc or 1.000.000ubtc you will ALWAYS have 1 of 21.000.000 of the total. Moving the decimal point is just that, nothing more. It affect everyone equally.
Very different is printing more money, if you have 1 dollar and the fed print some trillions of dollars, you still have just 1 dollar, but the total amount of money just increased. This means your dollar is worth much less. Now you have less of the total than before.
Another point of view: do 50.000grams weigh more than 50kilos? Or are they the same?
But I'm confused
50.000 grams, or 50 kilos
who in their right mind would say 50.000 doesn't way more than 50... It's a bigger number. Bigger means bigger. I'm bored, ignore this post xD
