They can outperform it on short term view, but they could never surpass the dominance and potential of Bitcoin.
The performance of those coin is just a hype, then look at the next thing happened with those coins once the hype collapsed. Usually they struggle to go up and cannot repeat those same good performance. While Bitcoin remains to be consistent and tested with so many pumps also dumps.
Those alts will continue to remain good for short term trades, then Bitcoin long term potential will also remain. That's why many people love to hold this for long term.
Of all the altcoins throughout history, only ETH has ever had a chance to surpass BTC in terms of market dominance, but it never managed to do so. As for other altcoins, there's no point in comparing them to BTC, especially for long-term holding.
However, it's also worth noting that altcoin growth isn't always driven solely by hype. Once again this year, the HYPE token is a clear example of that.
Yeah, alts are risky , and a lot of their gains are just hype, speculation and manipulation...but BTC isn't the only coin worth holding long term.
Whether we admit it or not, there are quite a few alts with serious development work behind them, real world use case, and longterm upside beyond a passing hype cycle.
Investing is about making money, after all. So it's not just about picking the coin that dominates the market. It's also about spotting assets with solid upside down the road.
