If you ask me I will say only buy Bitcoin but I see why latecomers are attracted elsewhere, there are other cryptocurrencies with unique features & potential for large growth. Diversification is key for some people, It is advisable to research & understand the potential of different cryptocurrencies considering factors such as technology, adoption & market trends. Each cryptocurrency offers different opportunities & risks so a balanced investment strategy that includes a mix of cryptocurrencies may be more beneficial for some in the long run.
I think there are a lot of parallels when people who have been in the bitcoin space for a long time, when asked, the answer is bitcoin.
But I also can't blame beginners for choosing alternative coins, because it is undeniable that many of them recognize bitcoin from alternative coins along the way. As happened to my friend, yes he came to me and asked further about bitcoin, after he knew other coins, even scam coins. I explained according to my ability and provided sources about bitcoin, and in the end he also preferred bitcoin after he was previously skeptical about bitcoin because of his previous experience.
There are only a few bitcoin maximalists who are able to boast that they have never invested in any other cryptocurrency. In the past, I had this argument and was disappointed with the names that came up. I don't want to be swayed by this narrative in the future. As far as cryptocurrency's risk management is concerned, Bitcoin has the best, and I recommend a good percentage in one's portfolio towards the bull market, but diversification will help test one's risk tolerance, but the chances of reward are usually good if it works out well.
