币界网报道：According to the news from CoinWorld, a16z Crypto published an article titled "Stablecoins: A 1+ billion-user onboarding opportunity", which pointed out that in the past 12 months, the transaction volume of stablecoins has reached 33 trillion US dollars, which continues to set new historical highs, close to 20 times the transaction volume of PayPal and close to 3 times the transaction volume of Visa. Stablecoins have been integrated into these huge global payment networks that have existed for decades. The booming development of stablecoins has brought the result that $128 billion of US Treasury bonds are held by stablecoins. This makes them among the top 20 holders of US Treasury bonds, even surpassing countries such as Saudi Arabia, South Korea, the United Arab Emirates and Germany. Citibank recently predicted that by 2030, stablecoin holdings in US Treasury bonds will reach 3.7 trillion US dollars, making it the largest holder on this list. Stablecoins have long been criticized for being used only to settle speculative cryptocurrency transactions, but data shows that this is not the case.
