Altcoins Cratered in Oct. 10 Crypto Flash Crash as Bitcoin Held Up, Wiston Capital Says

Friday’s crypto sell-off was a fast, leverage-driven cascade that crushed altcoins while bitcoin held up comparatively better — and the next phase hinges on a handful of signals, according to Wiston Capital Founder Charlie ￰0￱ a Sunday post titled “Crypto Crumble,” Erith said the market excluding bitcoin, ether and stablecoins fell about 33% in roughly 25 minutes on Oct. 10 before bouncing to a loss of around 10.6%. He added that about $560 billion, or 13.1%, has been erased from total crypto market value since Oct. 6 and cited $18.7 billion in liquidations during the ￰1￱ linked the immediate trigger to President Donald Trump’s Truth Social threat of an additional 100% tariff on Chinese imports, but argued the slide was already in motion — equities were still climbing while crypto “felt distinctly frail,” a divergence he took as advance warning.

Bitcoin, he said, “behaved largely as expected.” It fell, but less than the long tail, leaving bitcoin near a long-running uptrend from late 2022 and boosting its market share as non-bitcoin tokens absorbed “immense technical damage.” Erith said his fund emerged “largely unscathed” because positioning had already been defensively ￰2￱ Erith is watching next Erith said he is tracking bitcoin’s 365-day exponential moving average as a line that separates bullish from corrective ￰3￱ added that a pullback toward the $100,000 area and a touch of that average would not, by itself, overturn his longer-term view provided the level holds — but a sustained break would raise the risk of a deeper ￰4￱ also pointed to market breadth via bitcoin’s share of total crypto ￰5￱ to Erith, the sell-off accelerated a rotation toward higher-liquidity assets, lifting bitcoin ￰6￱ said a continued rise in that share alongside weak breadth would argue for caution in high-beta tokens until non-bitcoin charts ￰7￱ bitcoin’s own levels, Erith highlighted Strategy’s equity as a proxy for leverage and sentiment in the ￰8￱ noted that roughly four years ago a decisive move below its 365-day average preceded a major bitcoin ￰9￱ his view, holding above that trend line would support the resilience narrative; a break below could foreshadow renewed selling ￰10￱ is the other ￰11￱ said the VIX — the equity “fear index” — has started to climb and that historically better entries arrive when volatility spikes rather than during the early ￰12￱ framing implies patience on adding risk while equity-volatility stress plays ￰13￱ positioning, Erith said he remains invested but is avoiding leverage and is carrying cash “waiting for the dust to settle.” He said moves of this sort have, in his experience, sometimes preceded broader downturns, which is why he prefers to see the above signals stabilize before increasing ￰14￱ said the sell-off inflicted heavy damage on altcoins, while bitcoin’s month-to-date decline is modest and comparable to large-cap tech, which he views as evidence of growing resilience.
