In the top ten by market capitalization in the cryptocurrency space, there are two stablecoins, USDT and USDC. Among them, USDT is also the third-ranked cryptocurrency by market capitalization, which shows that the importance of stablecoins in trading is very high. Making money with stablecoins is like extracting oil from pork; you bring a piece of fatty pork into the refrigerator, and it looks like the pork hasn't decreased in size, but you end up with an extra layer of fat on your hands. This is also the reason why so many institutions and regions want to get involved. However, backing stablecoins is crucial; without strong support, news of defaults can strike unpredictably, as seen with USDT's negative news in previous years!
