A year after a big crash, BTC/ETH liquidity recovered, altcoins haven't

No clear lean
Good news for major coins, lingering risk for smaller ones
What happened

About a year ago, a sudden market crash wiped out a lot of trading activity across crypto. Since then, bitcoin and ether have gotten back to healthy trading conditions, meaning you can buy or sell decent amounts without the price jumping around too much. Smaller coins (altcoins) haven't recovered the same way and are more fragile if something shakes the market again.

Why it matters

If you hold bitcoin or ether, this is a sign the market around them is sturdier than a year ago; if you hold smaller altcoins, it's a reminder they can be harder to sell quickly at a fair price during stress.

Should I do anything?

Nothing urgent here. This is more useful as context for understanding risk differences between big coins and smaller ones, not a signal to act on.
