Not everyone will support Bitcoin of course. We've seen such behaviour in our daily lives; just like not everyone likes you. Another example is Mark Cuban; an American billionaire entrepreneur. In 2017, he said that you should "only invest in bitcoin if youre prepared to lose your money". We all know that bitcoin is volatile can that 'can cause' loss of your funds but... That statement is like saying you shouldn't invest in Bitcoin. Now earlier this year, in April, Cuban said that he'd rather have bananas than bitcoin. Now, in December, he said that his thoughts about Bitcoin hasn't changed.
Well, it isn't exactly wrong back then if you take a look at some of the events around Bitcoin. Everyone is entitled to their own opinion, and honestly, Bitcoin is seen as a volatile asset and then the bubble popping making quite a lot of people lose possible profits, it isn't really something rare that some view Bitcoin negatively. It is for a fact though, that long-term investment in Bitcoin has shown positive growth so far, but there's a different perspective for each person after all. Just let it go tbh, nothing we can do, it is for a fact that Bitcoin is volatile, and there's always a 50/50 chance of you losing money.
Having your own opinion should be fine and all, as long as you made that own opinion on your own ofc, without any influence of other personalities. You can reference them, but that's the limit, don't let it influence you, though it's kinda difficult but eh, I'm pretty sure most of us here are doing that anyway.
