That's because it is the first crypto. Also, it's not the one who get a good influence but it was the ones who influence others. Did you noticed that whatever happens to its price, other cryptos will then follow it? With that said, who will ever think that investing in Bitcoin is wrong?
I never thought it was wrong to invest in Bitcoin and in fact I very rarely care about those who still have bad things to say about Bitcoin. And I have also noticed very often that altcoin prices very often follow the flow of Bitcoin in terms of increasing and decreasing in the market. So it's still very normal for me that I'm still very happy to invest in Bitcoin now.
I think those people never heard of Bitcoin before and are still skeptical about it. When it comes to profits or ROI, many are saying that altcoins and tokens can provide it more than Bitcoin. I think it's true for a short time only but in the long term, Bitcoin can still win because Bitcoin is one of the coins that will remain while many of the altcoins and tokens will just disappear.
Those who have never heard of Bitcoin before and are still skeptical about Bitcoin will eventually lose because they believe too much in altcoins, because Bitcoin still has a better and longer future and will never disappear like altcoins. So it doesn't matter if there are still people who are skeptical of Bitcoin because one day they too will love Bitcoin and own it for the long term.
