gold is hard to move around, weighs a lot, it's hard to sell or buy, it's not practicable.
With BTC it's another story. We all know there are only 21,000,000 coins and 3-4 millions are already lost forever.
There is no Bitcoin in the whole Universe, except on Planet Earth.
BTC is scarcer than gold. I think one day 1 BTC will enter the $xxx,xxx zone then the $x,xxx,xxx HODL BTC
Before I see this thread I already know this fact. Common sense is enough to know this. The supply of gold is unknown while the supply of btc is limited to 21m only. There might be gold's on an asteroid but it will be very risky to get them because asteroids are I think moving very fast and don't hope that there would be some asteroid that will fell on the ground because it is too damaging.
Gold is hard to move around it is true for larger chunks but if it's only small? It is going to be easy and we have many pawnshops around us that accept gold. Aside from earth, we can also live on mars so it is also possible to carry our bitcoins there. As long as there is internet bitcoins is also functional.
