These past few days, altcoins have been performing exceptionally well, with IRYS showing dozens of times its initial value in a single day. There are also BIRB, BMT, and Order coins showing several times their initial value. Actually, the overall market performance has been mediocre for the past two days. It's just that these altcoins have repeatedly disregarded Bitcoin's performance. As for altcoins with alpha contracts, there will be intermittent price movements, but most market participants no longer have the ability to identify and capitalize on these opportunities. Therefore, whether Bitcoin has bottomed out or not is not that important anymore; it's a matter of existing funds playing against each other. The correlation effect is also weak; unlike the previous sector-wide surge, Bitcoin is generally still experiencing wide-range fluctuations.
