There is a valid point—non-USD stablecoins do have limitations from a savings and investment perspective. But this argument overlooks the most critical mission of stablecoins: they are not just an asset safe haven, but a means to redefine the global flow of currency. The ultimate goal of stablecoins is to accelerate the efficiency of capital circulation worldwide and break free from the constraints of the traditional financial system. Judging them solely from the perspective of asset appreciation is like only seeing the tip of the iceberg.
