Economy and stablecoins are two different things, from all sides, if you ask me whether (USDT), USD (USDC), and USD (BUSD, can the world economy be stable, the answer is no.
As far as I know the crypto market and the real market are different things, not everyone uses stablecoins, only certain ones, as well as the crypto market, not all of us use them, so how can stablecoins stabilize the world economy, we are aware that stablecoins only exist in the crypto market, whereas to stabilize the economy there are many things that must be done, that can happen in real activities, not in internet activities.
Things that need to be done to stabilize the economy are:
Economic stability is the basis for achieving an increase in people's welfare, namely through increasing high economic growth.
Economic stability will be achieved when there is a balance or continuity between domestic demand and domestic spending, saving and investment.
stablecoins have no impact and influence in achieving the Economic Stability milestone.
