币界网报道：Altcoin enthusiasm appears to be waning as Bitcoin's market dominance climbs to 33%, signaling a potential shift in investor sentiment. While altcoins previously saw significant gains during market rallies, recent data shows Bitcoin outperforming most alternative cryptocurrencies. Analysts attribute this trend to institutional investors favoring Bitcoin's relative stability and established position as digital gold. The growing dominance also coincides with reduced trading volumes across altcoin markets, suggesting decreased retail participation. Some market observers note this pattern historically precedes periods of Bitcoin-led bull runs, where capital eventually rotates back into altcoins. However, others caution that regulatory uncertainties surrounding many alt projects may be driving more conservative allocation strategies among both institutional and retail investors. The current market structure contrasts sharply with previous cycles where altcoins typically gained momentum following Bitcoin price surges.
