Layer-2 and DeFi Tokens Lead Crypto Rally as Altcoin Season Index Climbs

By Dawn Pennington

Bitcoin's been the story of this cycle. This week, something shifted.

Friday's rally had a clear leader, and it wasn't Bitcoin. Layer-2 and DeFi tokens took over, with the DeFi Select Index surging 8.3% since midnight and 16% over 24 hours.

Among individual names:

• Starknet (STRK): up 18% on the day, 21% over 24 hours — its highest level since June 19.
• Arbitrum (ARB): up 17% and 25% over the same windows — hasn't been this expensive since January.
• Uniswap (UNI): up 13% to 25% depending on the window, with futures open interest surging to 86.6 million tokens, flirting with an all-time high.
• Stacks (STX) and Optimism (OP): also posted solid gains, up 9.2% and 8.9% respectively.

Bitcoin (BTC), meanwhile, rose a more modest 2.1% to reclaim $78,000 — still about 5% below its Sept. 4 high.

The clearest signal of the shift: CoinMarketCap's “Altcoin Season” Index climbed to 44 out of 100, up sharply from Tuesday's low of 32. 

The Weiss Small-Cap Crypto Index, exclusive to Mark’s Next Crypto Superstars members, shows the same.

That's a real, measurable rotation in market character, not just a few tokens having a good day.

Mark Called the Setup

Our own Mark Gough flagged this rotation ahead of the move.

As he just told me:

“For now, alts are leading the move. They have been since BTC made a new low in July, whereas most alts didn't breach their June lows. But they dropped a lot more than BTC, so a short squeeze and/or rerating is expected.”

That's exactly what played out. 

Altcoins underperformed Bitcoin on the way down.

This set up the conditions for them to outperform sharply once sentiment turned.

Mark's forward view is where it gets interesting for positioning:

“Hopefully the good news and rules from the CFTC and SEC keep coming and drive alts further. 

“BTC stole the limelight in the last cycle: big ETF flows, media, and Trump with BTC reserve plans, etc. 

“This could be the alts cycle; we expect more institutional play in tokenized and DeFi, along with regulated crypto IPOs.”

Meanwhile …

Juan's Been Saying This for Weeks

Mark's read on the tactical rotation lines up with something Juan Villaverde told Weiss Crypto Portfolio subscribers on a live call last week. 

Asked about Ethereum (ETH) and Solana (SOL) specifically, Juan laid out the structural case for why alts should keep outperforming as this cycle matures:

“As the market bottoms out, I do expect both Ethereum and Solana to do better than Bitcoin ... 

“Ethereum is trading above its last 320-day-cycle high ... consolidating just above that 320 top. That's bullish ... Ethereum and Solana right now are much more bullish [than Bitcoin]. 

“That's a good thing because what it tells me is that as this next bull market warms up, these two guys are probably gonna do a lot better than Bitcoin on the way up.”

Juan expects Ethereum and Solana to outperform Bitcoin by roughly 50% on the way up over the next two years — the mirror image of how they fell 70%–80% during the bear market versus Bitcoin's 50%.

Juan also pointed to why institutions specifically gravitate toward Ethereum over other chains, which matters given this past week's SEC tokenization news:

“Wall Street doesn't build on sh*tcoins or small-cap altcoins. They build on time-tested, battle-tested infrastructure. 

“And that's Ethereum, not even Solana, just Ethereum ... if you want to bet on Wall Street moving into crypto, your best bet is Ethereum and Solana partly, too.”

The Macro Backdrop Helped

This wasn't happening in a vacuum. The 10-year Treasury yield slipped back below 5%, and Brent crude eased under $103 after trading as high as $109 earlier in the week — both easing the inflation scare that followed Wednesday's Fed rate hike. 

Risk appetite broadly returned: Equity futures firmed; gold and silver both gained too.

Why Regulation Is Showing Up in the Flows

CoinDesk's own reporting connected the dots directly:

“This renewed appetite for major DeFi altcoins stems from mounting market optimism surrounding friendly, coordinated crypto regulations from the SEC and CFTC.”

That's the same thesis we've been tracking all week. 

Now it's showing up as actual capital flowing into DeFi and Layer-2 tokens specifically — not just Coinbase and Chainlink, and not just Ethereum and Solana, but the broader infrastructure layer Juan has been pointing to for institutional adoption.

Positioning Signals Worth Watching

• Cumulative futures open interest expanded nearly 5% to $141.2 billion even as daily trading volume dipped — a sign capital is entering structurally, not through aggressive momentum chasing.
• Bitcoin's implied volatility (BVIV) dropped to 36%, a floor it's held since May, suggesting the market expects near-term calm now that Clarity, the Fed, and the Bank of Japan's rate decision are all in the rearview mirror.
• Options skew on BTC and ETH turned short-term bullish on Deribit, though one- and two-month skews still show a slight bias toward puts — near-term optimism, longer-term caution.

The Bottom Line

Bitcoin dominated the last cycle's narrative: ETF flows, media attention, Trump's reserve plans. Two of our analysts, working from very different timeframes, are now pointing at the same conclusion …

Mark's short-term technical read on the rotation, and Juan's structural, multiyear case for why Ethereum and Solana specifically should keep outperforming as institutional money moves in.

Friday's numbers are the first real evidence that thesis is starting to play out in price, not just in talking points.

To your health and wealth,
