Solana is testing a critical $100–$105 support zone after an aggressive sell-off reportedly accelerated by broader crypto market weakness. Currently, SOL trades at $102.5, down 2.6% in the last 24 hours and more than 15% over the past seven days, as downside momentum intensified. The move unfolds as Bitcoin broke below $80,000, reinforcing a risk-off backdrop across large-cap altcoins.
Volume expanded alongside the decline, signaling active distribution rather than low-liquidity drift. That matters for traders because high-volume sell-offs tend to confirm trend continuation unless buyers step in decisively at support.
Why Is the $100 Level Technically Critical for SOL?
The $100–$105 zone has acted as a recurring reaction area since mid-2024, repeatedly marking both local bottoms and failed breakdowns. Losing this level on a weekly close would represent a structural shift, opening downside toward the $90–$92 band and, in a higher-risk scenario, the $80 region flagged by weekly market structure.
On the daily chart, SOL lost the $120 support last week and failed to hold a rebound above $115, a level now acting as near-term resistance. The 14-day RSI sits near 28, approaching oversold territory, while MACD remains firmly negative, reflecting persistent bearish momentum rather than a confirmed reversal.

Solana Weakness Mirrors the Broader Crypto Sell-Off
Solana’s decline closely tracks the broader crypto sell-off, where Bitcoin fell nearly 20% from mid-January highs and printed a deeply oversold daily RSI of 22.03. Historically, SOL tends to amplify Bitcoin’s downside moves, which explains the outsized percentage drop as BTC threatens supports between $75,130 and $69,500.
Macro divergence adds pressure. US equity indices hover near all-time highs, while crypto assets continue to deleverage, a dynamic explored in recent coverage of the broader crypto sell-off. For SOL traders, Bitcoin holding above $75,000 is a key condition for any sustained bounce above $100.
Market Structure Flags an $80 Risk Zone
From a market structure perspective, the rejection from $140–$145 in January marked a lower high on the weekly chart. That sequence—lower high followed by a sharp breakdown—often precedes a deeper retracement toward prior consolidation zones, which for Solana cluster around $80.
No Solana-specific on-chain flow data has shifted meaningfully in the past week, limiting visibility into whale accumulation or exchange supply changes. In the absence of bullish on-chain confirmation, price action and volume remain the primary signals, both of which currently favor sellers.
What Could Invalidate the Bearish Setup?
The primary counter-argument is exhaustion selling. SOL’s RSI nearing oversold levels and Bitcoin trading below its lower Bollinger Band increase the probability of a relief rally. A high-volume reclaim of $115 would be the first signal that short-term control is shifting back to buyers. Similarly, Crypto Trader Max Trades believed that the price would attempt to bounce back to $110 – $115 in the coming weeks.

Until then, Solana remains vulnerable relative to peers like Ethereum, which is testing $2,300 support with a more contained structure. Traders comparing layer-one exposure may look to broader altcoin market conditions and the evolving Solana market outlook for relative strength signals.
For now, $100 is the line that matters. Holding it could invite a corrective bounce toward $110–$115, but a confirmed breakdown would shift focus decisively toward $90 and potentially $80, especially if Bitcoin fails to stabilize above its own key supports.
