South Korea, a globally active retail cryptocurrency market, is witnessing subtle yet significant market dynamics pointing to a powerful force lurking in the depths of the market – large-scale investors who have been quietly accumulating positions. Data indicates that these 'whale' investors have been absorbing selling pressure from retail traders for over three years, building a foundation for substantial altcoin price surges.
Compared to the relatively subdued market signals from 2019 to 2020, the current market cycle exhibits notably positive signs. Since the beginning of 2023, green signal bars, representing strong buying support (defined as 30-day trading volume consistently exceeding the 365-day average), have been persistently present. Simultaneously, yellow signals, indicating an upward trend in altcoin trading volume, have reappeared repeatedly and are becoming more frequent between 2025 and 2026.
Notably, even when excluding the top four largest market cap altcoins, the total altcoin trading volume in the Korean Won (KRW) market during this cycle far surpasses comparable data from the period preceding the last bull run.
This pattern of large buyers establishing sustained buying support while absorbing retail selling pressure is one of the more reliable indicators in cryptocurrency on-chain signal analysis. While it doesn't guarantee an imminent price surge, it clearly indicates that the conditions for significant price appreciation are being methodically constructed over a longer time horizon.
The South Korean market's influence in the altcoin space is particularly pronounced because, during periods of higher risk appetite, South Korean retail investors tend to be more aggressive and concentrate their investments in smaller-cap assets. When this retail wave surges, whales who have been accumulating on the other end for years will have the opportunity to profit from the surge in liquidity brought by retail traders.
The current situation also unfolds against a more favorable macroeconomic backdrop than any period in recent years. Regulatory clarity from the U.S. Securities and Exchange Commission (SEC) and the Commodity Futures Trading Commission (CFTC) has removed major structural barriers hindering institutional and retail participation in the altcoin market. The total value locked (TVL) in Decentralized Finance (DeFi News) has once again surpassed $100 billion. The U.S. has launched ETF products for multiple altcoins. It can be said that the infrastructure for the altcoin cycle is more complete than ever before.
While charts cannot predict the exact timing of the altcoin season's launch, they reveal that the accumulation phase, which typically forms the basis for major altcoin rallies, has lasted longer in this cycle and has been executed with greater resolve than in the previous one.
Data provided by cryptocurrency analytics firm CryptoQuant shows structural similarities between these two market cycles: a period of prolonged calm accumulation followed by an explosive expansion in trading volume. The 2021 cycle gave rise to some of the highest-returning altcoins in cryptocurrency history. Whether this cycle can match that performance remains to be seen, but South Korean exchanges are laying a solid foundation for potentially significant market shifts ahead.
