So yeah, probably this is true if other coins (Altcoins) didn't exist, so there is no doubt that people didn't seem to be the eye of Disney towards the cryptocurrency market. Because there are no fears in the market that some altcoins and shitcoins have created. Obviously, dude, if you look at the thing covered with the most risk in the market, it is not so much volatility as it is from scams and rug pulls, while volatility can also give you a return on increasing your price. But even who will not be able to return the scam and the rug pull-up? Those people are hungry to steal money, so how will they be able to give you a return? Although Bitcoin is a volatile thing, despite that, it can give you a return for increasing its price, and there is no concept of lack of security or scam in Bitcoin, and it can't threaten you when you keep it safe, like a wallet (hardware wallet).

So, in my opinion, these were some of the reasons for which I understand and agree with you that if there were no Altcoins and shitcoins in the crypto market, then people would invest in crypto without hesitation and would not be afraid the same way. Which is now shitcoin scare by scam, and even altcoin is included, like Tara Luna. I hope I have explained the topic correctly.
