Memecoin dominance relative to the broader altcoin market has fallen to 3.7%, its lowest since February 2024, according to CryptoQuant analyst Darkfost. The ratio had surged past 10% during the November 2024 memecoin mania, highlighting a sharp pullback in speculative appetite. The decline suggests a dwindling base of memecoin holders as capital rotates out of highly speculative tokens. The data underscores a broader cooling in risk-on sentiment across Asian retail crypto markets, where memecoin trading activity has historically concentrated.

Vietnamese authorities have seized more than 350 kilograms of gold and silver and frozen over 300 bank accounts linked to the ONUS crypto platform scam, local media reported.

The case highlights growing regulatory scrutiny in Southeast Asia as cryptocurrency scams proliferate across the region.

South Korea's five largest crypto exchanges — Upbit, Bithumb, Coinone, Korbit and Gopax — added only 117 new tokens in the first half of the year, a 44% decline from the same period last year, while terminations of existing listings surged 258% to 68 tokens. The net increase of listed tokens plummeted 74% to 49. The shift reflects a strategic pivot by Korean exchanges to prioritize liquidity management and tighten listing standards rather than chasing volume through new token listings. The trend is being closely watched by Asia’s trading community as South Korea remains a bellwether for altcoin sentiment.

Funds were traced moving to a single address in a laundering pattern, and one affected wallet transferred out an additional $2 million hours after a warning was posted. The incident underscores persistent security risks for crypto users in Asia, where older wallet software remains in widespread use.
