Ether (ETH) and dogecoin (DOGE) led majors gains on Wednesday with a 9% jump in the past 24 hours, extending a bullish streak that’s seen both tokens gain double digits over the past week.

The broader crypto market showed modest gains with total capitalization up 1.7%, per CoinGecko, with bitcoin (BTC) hovering around $103,700 in Asian morning hours.

Ethereum traded above $2,600, with dogecoin around 24 cents. XRP, BNB Chain’s BNB, Cardano’s ADA and Solana’s SOL gained between 3%-5%.

Despite a burst of green across major altcoins, crypto traders are starting to feel the weight of macro markets and warn of profit-taking in the short term. A stronger dollar and renewed trade tensions temper momentum, even as bitcoin flirts with record territory.

“The strengthening dollar on news of tariffs has been a natural drag on cryptos,” explained Alex Kuptsikevich, chief market analyst at FxPro, in an email to CoinDesk. “This is doubly true due to bitcoin’s proximity to the highs, reinforcing the pull for short-term profit taking after rallying in just over a month.”

As global markets shift from protectionism to cautious optimism, bitcoin remains in limbo. The asset is once again caught between competing narratives for some trader.

«BTC remains caught in a tug-of-war between its identity as “digital gold” and its function as a risk-on proxy,» traders at Singapore-based QCP Capital said in a market broadcast. «This tension continues to obscure its directional conviction. As the macro narrative moves from protectionism toward renewed trade optimism, BTC could remain range-bound.»

Still, sentiment remains strong. The widely-tracked Fear & Greed Index has held steady above 70 for four consecutive days — a “greed” level typically associated with sustained bullish appetite in the near term.

“Bitcoin showed its unpredictable nature on Monday,” Kuptsikevich added. “But with the positivity remaining, it’s worth paying attention to the price dynamics near $105. Will we see an acceleration or a new failure? The answer will guide the coming days.”

Elsewhere, latest fund flow data from CoinShares shows $882 million in institutional inflows last week — the third straight week of strong buying.

BTC led with $867 million, while ETH saw just over $1.8 million in flows despite a stellar price performance over the last week. Notably, Solana (SOL) posted $3.4 million in outflows, even as traders loaded up on $200 call options expiring in late June, as reported.

Quantum computing poses a real threat to crypto, and slow-moving governance processes risk leaving blockchains vulnerable, according to Colton Dillion, a co-founder of Quip Network, which provides quantum-proof vaults for storing digital assets.

While the technology, which uses the quantum states of subatomic particles to perform calculations instead of transistors and binary code, is still in its infancy, companies including Google and Microsoft are pressing forward with research and development. The goal is a massive step-up in speed that makes tough calculations like cracking encryption, such as that used to protect blockchains, faster and simpler.

And when quantum computing becomes available, any attacker is unlikely to announce their presence immediately.

“The threat won’t start with Satoshi’s keys getting stolen,» Dillion said in an interview. “The real quantum attack will look subtle, quiet, and gradual, like whales casually moving funds. By the time everyone realizes what’s happening, it’ll be too late.»

Dillion’s doomsday scenario involves a quantum-computing-powered double-spend attack. In theory, quantum computing could reduce the mining power required for a traditional 51% attack down to about 26%, Dillion said.

«So now you’ve compromised the 10,000 largest wallets. You rewind the chain, liquidate those 10,000 largest wallets, then double spend all the transactions, and now you’ve really got a nuclear bomb,” is how he imagines it.

The industry, of course, is working to find a solution.

Bitcoin developer Agustin Cruz, for instance, proposed QRAMP, a Bitcoin Improvement Proposal (BIP) that mandates a hard-fork migration to quantum-secure addresses. Quantum startup BTQ has proposed replacing the proof-of-work consensus system that underpins the original blockchain entirely with quantum-native consensus.

The problem is that the proposals must gain community approval. Blockchain governance, such as Bitcoin Improvement Proposals (BIPs) and their Ethereum equivalents, Ethereum Improvement Proposals (EIPs), tends to be rife with politics, making it a long, inherently cautious process.

For example, the Bitcoin community’s recent resolution on the OP_RETURN function was years in the making, with months of developer debates about what’s considered the «proper» use of the blockchain. Ethereum’s upgrades, like the Merge, also faced lengthy debates and delays.

Dillion argues that the governance process leaves crypto dangerously exposed because quantum computing threats will evolve much faster than the protocols can respond.

“Everyone’s trying to do this from the top down by starting with a BIP or an EIP and getting everyone’s buy-in together. But we think that this is a very difficult, heavy lift,” he said.

Quip Network’s quantum-proof vaults aim to circumvent the political inertia by allowing immediate user-level adoption without requiring protocol upgrades. The vaults leverage hybrid cryptography, blending classical cryptographic standards with quantum-resistant techniques to provide blockchain-agnostic security.

Effectively, they allow the whales, holders of large amounts of a cryptocurrency, to secure their stashes while waiting for the machinations of blockchain governance to get it together. Crypto communities can’t afford leisurely debates, he argues.

“The BIP and EIP processes are great for governance, but terrible for rapid threat response,” said Dillion. «When quantum hits, attackers won’t wait for community consensus.”

Shares of stock and crypto trading platform eToro (ETOR) have debuted at $52 a share after the company hit the Nasdaq exchange on Tuesday evening.

The company raised about $310 million from investors as it sold 6 million shares at a price of $52 a piece. The listing values the company at $4.2 billion.

The price is significantly higher than the marketed range, as the company received a much higher demand than previously anticipated.

EToro becomes the first company to go public after a rough couple of months in markets across the U.S., as President Donald Trump is in discussions to make several tariff deals with leaders around the world.

Because of that, many companies, including eToro, had delayed going public, but Bloomberg reported last week that the trading platform was resuming plans.

The company will trade under the ticker “ETOR”.
