IDK, im sure luna will bust sooner or later and kill terra, neutino on waves start to bust waves.
Algo coins are all bottlenecked to fiat trades. If this line breaks, they become unstable.
And this causes panic. The bigger this shit is, the more dangerous.
If they have no other use cases, it is unlikely that they are sustainable.
Once more commerce is done in stable coins, they can go on for a long time.
The frn has hung in there.
