100 Billion USD Wiped From Crypto in a Week as BTC, ETH and XRP Nosedive: What Altcoin Holders Do Now

Roughly 100 billion USD in market value has evaporated from the crypto market this week as BTC, ETH and XRP all turned sharply lower, per CoinPotato’s October 17 market wrap. For altcoin holders, the damage was worse than the headline suggests: while BTC slipped toward the 80,000 USD level it has now twice defended, high-beta altcoins took double-digit cuts as leveraged positions unwound and liquidity drained ahead of the weekend.

The wipeout caps a brutal stretch in which the “Uptober” narrative — the historically strong October that traders lean on — has failed to materialize. BTC is down nearly 4 percent month-to-date, an unusual break from seasonal pattern, and the broader market has followed it lower with leverage doing what leverage does: amplifying the move in both directions.

## What Actually Happened

The selloff was not a single flash event but a compounding series of pressures. Hot September inflation data (CPI at 3.7 percent) revived rate-hike fears and pushed up dollar yields, tightening financial conditions across risk assets. Crypto investment funds bled another 434 million USD in weekly outflows per CoinShares, extending the largest withdrawal streak of the quarter. And on Saturday, oil prices hitting 100 USD a barrel added a fresh inflationary worry to a market already priced for disappointment.

The result: total crypto market capitalization dropped by about 100 billion USD from its recent levels. BTC slid from the 84,000 USD area toward 80,000 USD, where it found a buy wall and rebounded to trade near 81,000-82,000 USD. ETH fell harder — roughly 10 percent for October — and XRP drifted toward 1.30 USD despite a stream of fundamentally bullish headlines.

## Altcoins Took the Heavier Hit

The defining feature of this drawdown is Bitcoin dominance hovering near 60 percent, a level from which altcoins have historically struggled to rally. When BTC sells off from that setup, altcoins do not just fall — they fall with the amplifier on:

– **SOL** trades near 104 USD, down about 1.8 percent on the day, holding better than most thanks to the Alpenglow upgrade vote on October 21 giving dip-buyers a date to anchor on.
– **HBAR** fell 8 percent on the week despite a 168 percent surge in network activity — fundamentals ignored in a risk-off tape.
– **SUI**, last month’s standout with a 49 percent gain, has given back ground as momentum traders rotated to the sidelines.
– **DOGE and other high-beta names** saw the sharpest liquidations, with cascading long wipes on derivatives venues amplifying spot weakness.

Liquidation data told the story plainly: over 1 billion USD in leveraged positions were wiped in the worst 24-hour stretch, with longs accounting for the overwhelming majority. Markets cleanse leverage like this periodically, and each cleanse resets the marginal buyer’s conviction.

## The Levels That Matter Now

Technically, the market sits at a decision point. BTC has twice bounced off the 80,000 USD level, where Glassnode has mapped a dense buy wall and liquidation cluster near 78,000 USD provides a second line of defense. ETF cost basis for the average holder sits near 81,500 USD — meaning the marginal institutional position is roughly at breakeven and, historically, inclined to defend rather than panic.

Above, reclaiming and holding 82,000 USD through the weekend would signal the correction is complete, with analysts pointing at 87,000-88,000 USD and then 94,000 USD as the next supply zones. Losing 80,000 USD on a daily close would invalidate that structure and open air toward the mid-70,000s.

For ETH, the 10 percent October decline has been tempered by one divergence: social sentiment remains positive even as price slides. The crowd being early is not a bottom signal in itself, but the combination of washed-out positioning and persistent belief has marked better entries than euphoria ever has.

## Why the Weekend Is the Tell

Saturday and Sunday liquidity is thin, and thin liquidity exaggerates moves in both directions. The weekly options expiry that cleared on Friday left dealers shorter gamma; the market’s first sustained push away from 80,000 USD will likely happen on weekend volume, and the direction of that push tends to set the tone for the following week.

Bull case: BTC holds 80,000 USD through the weekend, dominance rolls over, and the 100 billion USD that left the market returns selectively into oversold large-cap altcoins with catalysts — SOL with Alpenglow, XRP with its November 1 escrow release as a known event to trade around.

Bear case: oil at 100 USD keeps yields elevated, the ETF outflow streak extends into a fourth week, and 80,000 USD gives way, dragging total market cap toward the next 100 billion USD tranche lower.

## The Sober Takeaway

A 100 billion USD market-cap drawdown sounds apocalyptic, but context matters: crypto has shed trillions in past cycles and re-rated higher each time. What actually destroys altcoin investors is not drawdowns — it is being overleveraged into them. The traders wiped out this week were not the ones holding spot through volatility; they were the ones running 10x positions into a CPI print.

With BTC pinned at its most defended level of the quarter, the market is offering a textbook setup: patient, unleveraged accumulation zones for those who believe, and cheap options for those who want to define risk precisely. The next 48 hours of weekend price action will decide which narrative writes next week’s recap.
