Of course, investing all your money in Bitcoin sounds like a good idea compared to altcoin. However, based on investment principles, putting all your money into a single asset is a bad idea, no matter how great that asset's potential is.
Putting all money in a single asset will be bad if we choose the wrong asset. However, Bitcoin isn't a bad asset, it is the most recommended crypto coin. So, putting all money in Bitcoin only is quite reasonable. But I can agree that this will miss the opportunity to gain profits in altcoins. Well, it is actually a choice, each investor may have a different perspective about this. If you want to try luck in altcoins, you can divide your funds into altcoins as well.
in my opinion, you shouldnt go allin on Bitcoin, and even less so on altcoin, or better yet, not go allin on crypto at all. Instead, you should diversify by investing in asset outside of crypto.
IMO, there is no problem to invest in Bitcoin only. But I agree we shouldn't invest in a single altcoin, it isn't a wise way (especially on random altcoin).
Yep. Diversify assets in gold, property, or land will be a good option..
