Like many previous ETFs topics, people always question ETFs, some think it will have a negative impact on Bitcoin and don't like the appearance of ETFs...but the problem is we can't do anything to prevent it. So it really is a waste of time when we spend time talking about things we cannot change. And in my opinion, the existence of Altcoins will have a positive and negative impact on bitcoin, and what we need to do is adapt to it because we won't be able to do anything to change that even when we don't like it.
I'm not against predicting or speculating on the impact of new things like ETFs could have on the price and Bitcoin as a whole. And I'm all in favour of trying to identify any future threats that ETFs or altcoins can pose to Bitcoin, so we can maybe act to prevent such etc. But asking whether Bitcoin would be better off if no altcoins ever existed is a pointless thought exercise at best with no value to it. Unless people get entertained by having such discussions, then it's OK I guess.
I also don't object to people speculating or spending time discussing the negative impact of ETFs or altcoins because I can't stop people from doing that. What I'm saying is that it's a waste of time because we have no way to stop them even if they have a negative impact on bitcoin. Just like altcoins, as many people say it is negatively impacting bitcoin, what are you going to do to stop that? Do you have any way to stop the development and growth of ETH? Or BNB and even shitcoin? Is there any way to stop people from creating them every day? I prefer adaptation to resistance.
