The big USDT inflow basically shows traders are moving into defense mode. Instead of rotating aggressively into altcoins, money is sitting on the sidelines waiting for market conditions to calm down. What stands out is that Bitcoin volume actually increased during the drop. That usually means this isn't just passive weakness — traders are actively de-risking, closing longs, and opening fresh shorts while fear stays elevated. At the same time, on-chain activity still looks healthy, which makes this setup interesting. Historically, heavy stablecoin positioning can become fuel for a strong rebound once sentiment flips back bullish. Personally, I think this looks more like a temporary risk-off phase than a complete market breakdown. I'd stay cautious short term, but stablecoin sidelines also mean there's still plenty of capital ready to re-enter later.
