Today the market clearly weakened, and BTC dropped back below 80k.

I think the most important thing now is not how much it has fallen, but whether the 80k level holds again.
This level is no longer just an ordinary psychological threshold, but now acts as a short-term emotional anchor.
Once BTC drops back, mainstream altcoins like ETH, SOL, XRP, DOGE will immediately start to retrace together, indicating that market risk appetite is clearly decreasing.
And today, it's not just the price that looks weak, but the structure also looks poor:
Altcoins are more fragile than BTC, and assets like BNB, which were relatively resilient a few days ago, are also starting to loosen today;
Trading volume is still shrinking, indicating that it’s not “people aggressively buying at low levels,” but rather that many funds are choosing to wait and see.
So my current view is very simple:
As long as BTC cannot reclaim 80k, it will be difficult for the market to return to a comfortable rhythm of “BTC stabilizes, altcoins rotate.”
In the short term, it’s weak, the structure is deteriorating, and the focus should be on whether 80k can be recovered quickly later.
