We can also invest in altcoin because altcoin returns are bigger than bitcoin, but we need to know the right time to invest. Altcoins are not suitable for bear markets but should only be invested in bull markets and should be short-term investments. Bitcoin is safe in this bear season, bitcoin is suitable for long term.
This is indeed something that must be considered, but on the other hand, when we really don't want to take a bigger risk to be in altcoins, then of course the main choice is bitcoin, which is more promising because regardless of any conditions, such as a bear market, it is actually quite difficult to predict and this is not very good if you really want to try to do something especially for beginners who are just joining in.
Even though there are indeed some altcoins that are quite good, it still has a higher risk than bitcoin.
