I have an assumption that the era of USDT leadership is coming to an end. USDC is steadily reclaiming the market and the gap between the capitalization of these two assets has recently narrowed a lot, now about 11 billion. Most likely, investors saw some concerns about losing peg to the USD and started pouring liquidity into USDC in droves. USDT has not always been smooth with collateral, because judging by their audits, the collateral there was not fiat, but more in securities.
Thanks for this info, I haven't followed USDC though, as I put some of my assets in USDT right now so obviously, I'm more concern about this news. But as others have pointed out, this is DDOS attack and not on their reserves dwindling down or something.
And last time I check the price is still pegged as 1:1 so I'm will not be concern anymore. Yes, Bitifinex is shady as claim by some and says that they are running on fractional reserves only. But they have been in the market since 2017 or longer if I'm not mistaken, and so far no Luna like problem.
