Altcoins are making a strong move against Bitcoin lately. Since December 26th, the uptrend has been pretty solid—definitely worth watching. What's interesting here is the shift in market dynamics. We've seen plenty of cycles where a quick 48-hour surge gets followed by consecutive dumps that wipe out gains. But this time feels different. The market structure is actually holding up, which is a good indicator. When altcoins establish this kind of relative strength against BTC, it often signals a maturing rally rather than a flash pump. Keep an eye on how this consolidation plays out—the foundation matters more than the spike.
