So lately I've been thinking about the global financial economy and the way it works.

During my BA, I had a course with a professor that played a very high role in the central bank of Israel.
I asked him "Is the bank preferring for the day after the economy will collapse?" the answer he gave me was not clear. I saw him struggling to answer that.
But when I examine
Bitcoin and other crypto coins, I see it not as a replacement of money, but just as a replacement of the central bank money printing. Because eventually, we'll all look for a place to keep our money safe (a bank) and someone to give us a loan on occasion.
So my question is, is it really the future of the economy? or just the "new gold"?

What do you mean by "the future of the new economy"?
I don't think that any financial asset can be "the future" of a new economy.
The real future of the economy lies in technology innovations like producing cheap and clean electricity or replacing oil.Financial assets(even digital assets like cryptocurrencies) are a just a tool used for wealth re-distribution.Some people lose money on the markets,while others win money.It's zero sum game.
Bitcoin is an alternative to fiat and money printing,but that doesn't mean that it will totally replace fiat money some day.
