Bitcoin will crash the economies around the world one day.
BTC will crash when people realize it has limited usage, and its backed by Tether which cant pass an audit, and Micheal Saylor appears to be running a house of cards with Strategy. Other cryptos with utility will surpass it;
Fiat is crashing the economies of the world. Bitcoin will save it.
There is no reasonable argument for saying bitcoin will crash anything. Whereas fiat currencies like the dollar are constantly being inflated, are not scarce, and have a long history of hyperinflating (while bitcoin is deflationary). Every fiat currency dies an ugly death sooner or later, because politicians have every incentive to engage in deficit spending and monetize the debt until the money used is worthless.
Bitcoin breaks that cycle. We just need to use it and reject fiat.
