Dogecoin has lagged the broader crypto market in the current bull cycle, recording the weakest year-to-date performance among the top 10 coins while several smaller meme tokens have rallied. Analysts highlight five alternatives—Fartcoin, Pepe, Pippin, Maxi Doge, and Pepenode—which feature low to mid caps, high trading volumes or presale inflows, and in some cases staking rewards or on-chain activity that could support stronger upside into 2026. These projects span Solana- and Ethereum-based ecosystems and are being accumulated by so-called smart money investors looking for higher risk-reward opportunities.

Solana has been subjected to a distributed denial-of-service attack peaking at nearly 6 terabits per second, reportedly the fourth-largest incident ever recorded against a distributed system, yet its network continued processing transactions without disruption.

Bittensor completed its first halving, reducing daily issuance from 7,200 to 3,600 TAO amid rising institutional participation.

According to on-chain data from Ember, a large AI Agent-focused wallet has exited a basket of agent tokens bought for $31.12M, receiving just $2.57M and realizing a loss of about $28.54M.
