Is $SOL's reign over? Likely not.
But will there be periods in time when outperformance shifts between the most dominance chains? Absolutely.
Solana had a good run the last few years while $ETH lagged.
And before that it was the other way around when SOL lagged.
Today we are looking at that change in momentum again.
Charts (and also meme dominance subsiding) suggests Ethereum to likely be the better performer in the near future.
Can both still go up at the same time? If the entire market enjoys a period again when it moves to higher market cap then yes they will.
But one will still outperform the other. Choose wisely.
