I came across a post from three years ago.
Back then, BTC was 31,329; now BTC is 73,802.
Back then, BNB was 256; now BNB is 639.
And ETH remains quite stable.
Back then, it was 1,997; now it's 2,030.
That year's USDT was 7.2; this year's USDT is 6.8.
So the conclusion is that ETH is the real stablecoin.
