Bitcoin and Ether Order Books Recover, Altcoins Lag

Bitcoin and ether trading books are now thicker than before last year's flash crash, while altcoins have not caught up. If you hold a mixed wallet, that gap changes how safely you can trade smaller tokens.

What actually happened

On 10 October 2025, a sudden crash hit crypto markets, wiping out liquidity across the board. A year on, CoinDesk reports that bitcoin and ether order books have rebuilt past their pre-crash depth. Altcoin liquidity, by contrast, keeps thinning over the same stretch. Overall spot trading volume still sits well under its October 2025 high, per CoinDesk. The report treats bitcoin and ether as a separate bucket from altcoins in its comparison, but gives no exact depth numbers, volume totals, or named tokens. No exchange staff, market makers, or traders are quoted in the piece.

How we got here

Flash crashes act as stress tests for market structure. They expose which assets have reliable market makers standing behind them and which do not. Over the past 12 months, exchanges and liquidity providers appear to have focused rebuilding efforts on the two biggest coins by market value. Smaller tokens were left out of that repair work. The source report does not explain which firms returned, how exactly depth was measured, or why specific altcoins fell behind, so the mechanics behind this split remain unclear.

Why this matters for you

If you mostly hold bitcoin or ether in a bonuz wallet, larger trades should move the price less than they would have a year ago. If your wallet leans toward smaller altcoins, the opposite is true: thin books mean one big sell order can crash the price, and getting out fast during a dip gets harder. Anyone building or launching a new token now faces a tougher search for market makers willing to keep spreads tight. For everyday users holding a mixed bag of assets, this is a good moment to reconsider position sizes outside the two major coins.

The bigger question

If trading depth keeps concentrating in just bitcoin and ether, what happens to the thousands of smaller tokens that rely on active markets to function? That could reshape how ordinary holders think about spreading risk across a wallet.

What to watch

The CoinDesk report sets no specific follow-up date. Expect analysts to keep tracking order book depth and spot volume in coming months to see whether altcoin liquidity steadies or keeps slipping. Bonuz will keep following this liquidity split as part of its regular market coverage.
