Today in crypto: Hundreds of wallets on Ethereum Virtual Machine blockchains were drained in a broad exploit. Solana and BNB Chain topped Nansen’s list of the busiest blockchains of 2025, while CryptoQuant data suggests Bitcoin may already be in a bear market.
‘Hundreds’ of EVM wallets drained in mysterious attack: ZachXBT
An attacker has drained “hundreds” of crypto wallets on Ethereum Virtual Machine (EVM) chains, siphoning small sums from each victim in what onchain investigator ZachXBT described as a broad but low-value exploit.
The losses appear limited on a per-wallet basis, with each victim losing less than $2,000, according to ZachXBT. The activity has affected wallets on several EVM-compatible networks, indicating a widespread incident rather than isolated to a single blockchain.
A fraudulent email disguised as legitimate communication from Web3 wallet MetaMask could have been the vehicle for the attack, said cybersecurity researcher Vladimir S., who cited a clue left by another pseudonymous X user.
“This looks like automated, wide-net exploitation,” cybersecurity provider Hackless said, warning users to revoke smart contract approvals and continue monitoring their wallets.
The widespread wallet drain attacker is potentially linked to the Trust Wallet hack that occurred on Christmas, Vladimir S. said, citing another pseudonymous X user.
The 5 busiest blockchains of 2025 and what powered their growth
Onchain analytics firm Nansen ranked Solana, BNB Chain, Base, Tron and NEAR Protocol as the busiest blockchains in 2025.
Solana led the pack with 23.01 billion transactions, while BNB Chain followed with 3.89 billion. Coinbase’s Ethereum layer-2 Base handled 3.29 billion for third, as Tron trailed with 3.22 billion and NEAR came in fifth with 1.89 billion.
Even as 2025 was marked by institutional adoption, retail-focused use cases continued to dominate transaction volumes, particularly on blockchains with low fees and high throughput.
Solana’s dominance came on the back of a trading boom that pushed it to the top of decentralized exchange (DEX) rankings in early 2025.
CoinGecko reported that Solana DEX trading dominated 40% of the industry’s market share by recording $293.7 billion in the first quarter of 2025. It was driven in part by a memecoin frenzy around celebrity and political tokens like $TRUMP, a Solana-based token launched on Jan. 18 tied to US President Donald Trump.
Metric suggests Bitcoin has been in a bear market for 2 months
Bitcoin may already be two months into a bear market, according to certain metrics such as the one-year moving average, says CryptoQuant’s head of research.
During an episode of the Milk Road show on Thursday, CryptoQuant’s Julio Moreno said most of the metrics he uses for the bull score index turned bearish in early November and have yet to recover.
The index measures market conditions using indicators like network activity, investor profitability, Bitcoin demand, and liquidity, and ranges from 0 to 100.
“For me the last confirmation, it’s a technical indicator, which is the price going below its one-year moving average, that’s the technical indicator that I would say confirms this.”
A one-year moving average is the average price of an asset over 12 months, and used to show long-term trends.
Bitcoin is trading around $88,543 as of Friday; however, Moreno predicts that over the coming year, the bear market bottom will likely be in the $56,000 to $60,000 range, based on Bitcoin’s realized price and past performance.
