I watched a video telling that every paper currency in history all collapsed , and USD will collapse too, in future.
The time in which a currency collapses is when people don't believe in its value anymore. And obviously, when thought reversely, something becomes a currency when more and more people believe in its value.
And currency becomes money when they don't lose value between people regardless of time, like gold.
Do you believe btc could be in this position? BTC could become gold?
You are a bit confusing. Actually, a currency is a kind of money which is used by a certain country. You do not have to confuse money and currency. They are basically the same. The money that we all use has a specific currency and all currencies are money. Well, that would not include cryptocurrencies of course. Gold used to be the form of money before but then it became so valuable that it gradually turned into an asset. Much like Bitcoin.
