Altcoins include ethereum,polygon etc. Already heard of dying of altcoins. Many peoples invest in different platforms. Some people hold Ethereum polygon bnb etc. But their prices don't rise much. Are they better to hold and invest than Bitcoin? In my opinion, Bitcoin is the best to hold. We have all seen the volatile Bitcoin market in the past few months. It is rumoured that the price may rise further in 2024. Bitcoin never disappoints. I know some big brothers who invest or hold bitcoins never heard from them that investing in bitcoins is not good. Investing in bitcoins is better than spending money on a lover but it sounds ridiculous but it is true. So I say investing in bitcoins is better than investing in other fields. Bitcoin is the best.
You have done well by acknowledging the presence of other altcoins such as Ethereum and BNB, polygon etc and also mentioned Bitcoin which is something that assures me that you already know how both decentralized and centralized work and the profits potential of both Bitcoin and the other altcoins, one of the smartest way to survive in the cryptocurrency market is diversification of portfolio.
Giving priority to Bitcoin which means 50%+ of the total investment in Bitcoin and the remaining 50% in various altcoins according to the level of potential and risk level, because most of the altcoins as you already know find it hard to rise in price once they price crashed significantly but Ethereum have always been following Bitcoin footsteps and rising along Bitcoin each time and also fall when Bitcoin drop in prices which have made Ethereum to be one of the active altcoins in terms of market stability.
