Three low-market-cap altcoins have experienced significant price gains in December, driven by increased whale activity. Avantis (AVNT), a Base DEX token with a market cap of $89 million, saw substantial whale purchases totaling 11 million tokens, leading to a 4.9% decrease in exchange reserves. Similarly, Succinct (PROVE), a zero-knowledge proof network, reported a 5.34% increase in whale holdings. Plume Network (PLUME), a notable altcoin in the real-world asset (RWA) space, rebounded by 35% after whales acquired nearly 7 billion tokens. The CEO of Plume Network anticipates significant growth by 2026, reflecting strong investor confidence in the project's future potential.
