now I ask, who created gold? Nothing, God is the Creator and we can not prove His existence nor His true identity if it exists. So far, no single individual or company can create gold. To get gold, we have to mine it first or buy it from the nearest gold shop. These glorious metals are scattered throughout the world, applicable and can be traded in any country, although not created by a real figure. Gold is available in limited quantities, and this is what causes the price to increase over time.
Bitcoin is exactly like that, but the difference is that it is digital or invisible. So now imagine you've turned the gold into something virtual and stored on your computer or smartphone. Bitcoin has all the important aspects that gold has, but it looks like a pulse. Amazing, is not it?
Imagine when the aliens come to partner up and build a moon base and we say to them "sorry we don't use gold do u accept bitcoin?"
