BTC has a cheat-code in being the only US spot-ETF approved coin on the market. I think this continues to fuel its upwards dominance in the short-term.

Mid-term, crypto-native folks take profits, providing oxygen for altcoins, and a subsequent alt-season. ETH spot-ETF is also the big wildcard, but one has to assume it has a chance of passing (regardless, with ETH lagging in price, there's lot of room to fill).
