Solana just lost 11% in a week. The next seven days could decide whether that was a dip or a top.

Our Solana price prediction for the coming week: SOL at $107.35 could test $100 support before it challenges $120 again. That is the base case from the altFINS analysts after SOL was rejected at $120.

The bigger trend is still up, and the Alpenglow upgrade lands on October 21. Here is what the live altFINS data shows, the levels that matter, and how to trade either outcome.

Why Is Solana Down This Week?

Solana is down 11.10% this week because the whole altcoin market pulled back and SOL failed at $120 resistance. A sharp Bitcoin flush on October 13 then forced out leveraged traders.

Solana fund flows cooled too. US Solana funds posted $24.8 million of weekly outflows, ending a 14-week inflow streak.

There is one more level traders are watching. SkyAI, which holds about 600,000 SOL, said its tender offer could fail if SOL falls below $100. That makes $100 a psychological line as well as a chart level.

How Does Solana Compare With Other Large Caps?

SOL is one of the weaker large caps this week, but its trend is the same as the rest of the market. Every coin in the table below still has a rising medium-term trend.

SOL has the lowest RSI in the group at 41.6. That means sellers are in control short term, but it is not oversold yet. Zcash is the only coin here that is green today.

Solana Price Prediction: What Do the altFINS Analysts Expect?

The altFINS analysts expect SOL to revisit $100 support after a Double Top at $120. Their near-term outlook is Neutral because the uptrend is intact while the short-term trend has turned down.

Three scenarios for the next one to two weeks:

• Bullish: SOL holds $105 and a smooth Alpenglow launch lifts it back to $120. A close above $120 opens $145.
• Neutral: SOL chops between $100 and $115 while traders wait for the upgrade.
• Bearish: SOL breaks $100 and slides to the $90 zone. The 200-day average near $87 is the last big floor.

What Are the altFINS Signals Saying Right Now?

The signals are mixed but tilting toward a bounce. Overnight, the altFINS signal feed fired these alerts on SOL:

• Bullish: Uptrend and fresh bullish momentum (rising MACD histogram bars).
• Bullish: Tweezer Bottom candlestick and Pullback in Uptrend.
• Bearish: the 12-day EMA crossed below the 26-day EMA.

Momentum turning up while price sits near support is often how a pullback ends. It still needs confirmation from price. Track every live SOL signal on altFINS.

What Is the Alpenglow Upgrade and Why Does It Matter?

Alpenglow is a Solana upgrade set for October 21 that targets about 150-millisecond transaction finality. It replaces the current validator voting system.

One side effect is worth knowing. Vote transactions will be removed from blocks, so headline transaction counts may fall even if real activity stays flat. Do not read that drop as weak demand.

How Do You Trade Solana at $100 Support?

Wait for price to reach support, confirm it holds, and set your stop before you enter. Here is a simple plan built on the analysts’ levels.

1. Set an alert at $100. Do not buy halfway down.
2. Confirm the bounce. Look for a bullish candle or a rising MACD histogram at support.
3. Define the exit. A stop just under $90 support keeps the loss small.

Example: buying at $100 with a $89 stop risks $11 to make $20 at the $120 resistance. That is a 1.8-to-1 trade, so you can be wrong more often than right and still come out ahead.

Frequently Asked Questions

Why is Solana down this week?

Solana is down 11.10% this week because altcoins sold off after a strong September and a Bitcoin flush on October 13 cleared out leveraged traders. SOL was also rejected at $120 resistance, forming a Double Top that the altFINS analysts say could send price back to $100 support.

Will Solana go back up?

The medium- and long-term trends are still up, and SOL trades 23.1% above its 200-day moving average. Fresh altFINS signals show rising momentum and a Tweezer Bottom candle. A daily close back above $120 would signal the uptrend has resumed; a break below $100 would point to $90 first.

What is the Solana Alpenglow upgrade?

Alpenglow is a consensus upgrade scheduled for October 21. It replaces Solana’s current validator voting system and targets transaction finality of about 150 milliseconds. Vote transactions will no longer be stored in blocks, so headline transaction counts may drop even if real user activity stays the same.
