ETH Upgrade, BTC Bounce, and the Prediction Market Boom

The last 24 hours in crypto have been eventful: Ethereum's long-awaited Fusaka upgrade went live, Bitcoin reclaimed a key level, and interest in prediction markets is surging. While some see this as the start of a new rally, others view it as just a temporary relief.

Let's break down what actually happened and how these events are impacting your trading strategies.

1. Ethereum Is Now Faster and Cheaper: What the Fusaka Upgrade Delivers

The Fusaka upgrade has been activated, and its main feature is PeerDAS.

  • What this means in simple terms: For node operators, data storage costs are going down. For users on L2 networks, transactions are becoming faster and cheaper. The feeling of "near-instant" settlement is becoming a reality.
  • Market Impact: Lower costs boost liquidity on Layer 2s. Arbitrage becomes faster, market makers can operate with tighter spreads, and DEX volumes can grow without a spike in fees.

Practical Takeaway: If you're trading altcoins on L2s or arbitraging between L1 and L2, your old cost models are now obsolete. It's time to recalculate your economics.

2. Bitcoin Reclaims $93k: A Bear Trap or the Start of a Reversal?

Bitcoin saw a strong bounce, fueled by two key factors:

  1. A massive short squeeze: Traders who were betting on a price drop were forced to close their positions, pushing the price upward.
  2. Inflows into spot ETFs: Institutional capital continues to enter the market.

The Key Technical Level: The $92-93k zone.

  • If the price holds above this level, the path to $97-100k is open.
  • If it falls back below, the risk of a deeper correction rises sharply.

Practical Takeaway: Don't get carried away by the euphoria. Short squeezes provide a quick but temporary boost. The real move will begin when new, confident buyers enter the market. Keep an eye on ETF inflows and declining exchange reserves—these are more reliable signals.

3. Prediction Markets Are Back in the Game: From Kalshi to Polymarket

The news flow confirms it: prediction markets are returning to the mainstream.

  • What's happening: Kalshi has closed a major funding round, Polymarket is re-entering the US market after regulatory approval, and major brands like Fanatics are launching joint products with Crypto.com.
  • Why it matters: Prediction markets translate expectations (on politics, sports, economics) into a real price. The influx of capital and integration with major platforms (like MetaMask and Trust Wallet) are making these markets deeper and more liquid.

Practical Takeaway: New opportunities for event-based trading are emerging. But be cautious: regulatory risks in different jurisdictions could cause liquidity in a specific market to vanish faster than you can close your position.

4. DeFi Infrastructure Is Getting Smarter

Important technological shifts are happening in the background:

  • Native BTC in DeFi: The Aave protocol is integrating Bitcoin staking via Babylon. This will allow BTC to be used in DeFi without "wrapped" versions (like WBTC), reducing risks.
  • Simpler On-Ramps for Beginners: Uniswap is launching a fiat on-ramp with Revolut, simplifying crypto purchases for European users.
  • Transaction Insurance: MetaMask is offering a paid service called Transaction Shield to protect against certain types of fraud.

Practical Takeaway: The infrastructure is becoming more user-friendly and secure, which attracts new liquidity. New solutions like native BTC change risk models, and this needs to be factored into your portfolio.

Conclusion: How to Navigate a Changing Market

The market is in a phase of active transformation. The Ethereum upgrade is making L2s more attractive. Bitcoin has shown that short positions are still vulnerable to squeezes. And prediction markets, along with new DeFi tools, are creating new opportunities and risks.

What Coinrate readers should be doing:

  1. Monitor L2 metrics. Gas fees, transaction speeds, and batch sizes are the new rules of the game for arbitrage.
  2. Stay disciplined on Bitcoin. Position sizing and hedging are more important now than trying to catch a moonshot, especially around the $92-93k level.
  3. Explore new tools. Native BTC in DeFi and transaction insurance are changing risk assessments.
  4. Don't confuse noise with the trend. The market is far from calm. Those who can quickly read on-chain signals and manage risk will have the advantage.

Keep notifications on for key metrics, check liquidity before placing large orders, and don't panic when the market does its favorite job: punishing unwarranted optimism.
