If you are looking to hold for the long term, Bitcoin is the best option. Altcoin investments are riskier and you might lose all your money in a single dump. However, in the short term, you can make a good profit by investing in ETH, LTC, DOGE, etc.
Bitcoin is definitely a good option for long-term investment. Compared to altcoins, the risks involved in investing in Bitcoin are negligible. It's true that altcoins are often considered risky. I think there are still altcoins in the market that have the potential to make a good profit in the coming bull season. If you look at the last short period of time, there are some altcoins that have given people very good profits in a short period of time. For example Gala, Ocean Protocol and mastic showed a good rally.2 days ago, Solana increased its price to $32, which was trading at $8 a month ago. So Bitcoin has its own importance but the benefits of altcoins cannot be ignored.
When talking about long-term investment, we really can't ignore Bitcoin,
it is a really decent and safe coin for long term investment,
other than that a top coin like Ethereum is also a viable option in the long term.
