In the first week of December 2025, Coinbase—the largest US exchange—added five new assets to its listing roadmap. This move signaled a positive shift in recovering demand from US investors. Additionally, Bithumb listed new altcoins. Although market sentiment remains fearful. However, several indicators show that US investor appetite is improving. Coinbase and Bithumb Add New Altcoins In a new announcement, Coinbase revealed that five new assets have been added to its listing roadmap. The roadmap is a list of tokens that Coinbase is evaluating for potential future listing. Coinbase emphasized that listing depends on support from market makers and the availability of sufficient technical infrastructure. The exchange will announce the trading schedule later. The newly added altcoins include: Humidifi (WET) – the largest decentralized exchange (DEX) on Solana by volume, handling over $1 billion in daily trading. zkPass (ZKP) on Ethereum (ERC-20), known for zero-knowledge proof technology that enhances data privacy. Plume (PLUME) on Ethereum, an RWAfi (Real World Assets Finance) platform integrating with Circle’s Arc testnet. It aims to connect traditional finance with DeFi. Hyperlane (HYPER) on the Base network, enabling cross-chain communication. Jupiter (JUPITER) on Solana, the leading DEX aggregator in the Solana ecosystem. Among them, Humidifi (WET) and zkPass (ZKP) remain largely unlisted on centralized exchanges. The remaining altcoins showed no significant price reactions after the news.

BOB, TRAC Price Performance. Source: TradingView BOB is a protocol that combines ZK proofs and BTC staking to create native bridges to Ethereum and Bitcoin (BitVM). OriginTrail is an ecosystem building a trusted knowledge infrastructure for artificial intelligence. After the listing news, BOB gained 24% and TRAC rose more than 13%. Liquidity Signals Turn Positive Again These developments came as the Coinbase Premium Index—an indicator measuring the price difference of Bitcoin between Coinbase and other exchanges, representing US investor demand—turned positive again after remaining negative for a full month.

The early-December reversal suggests that sentiment among both institutional and retail investors in the US is improving. This shift may support inflows not only into Bitcoin but also into other cryptocurrencies. “Coinbase Bitcoin Premium Index just flipped positive again, showing fresh demand… US liquidity returning & the real move begins soon,” investor Money Ape commented. At the same time, the stablecoin market recorded strong growth, reinforcing confidence in an overall recovery. According to Lookonchain, Tether minted an additional 1 billion USDT on Tron on December 3. This pushed the stablecoin market cap on Tron above $80.2 billion. As a result, total stablecoin market capitalization began rising again in early December after declining throughout November. It now stands at more than $306.85 billion, according to DefiLlama.

Coinbase and Bithumb’s addition of New Altcoins, combined with strengthening US investor demand and surging stablecoin inflows, may trigger an altcoin recovery in December. Some analysts even argue that the Fed ending quantitative tightening (QT) could ignite a multi-year altcoin rally similar to the 2019–2022 period.In the first week of December 2025, Coinbase—the largest US exchange—added five new assets to its listing roadmap.
