That's why you don't follow any crypto enthusiasts in twitter. Or any other social media for that. Heck, I'd trust answers here than there tbh, since most of them out there are just there to take advantage of Bitcoin for money-making. I'd rather follow accounts that actually bring in some sort of useful info, such as market news or coin movements, my time is a lot more well spent seeing those tweets than seeing a bunch of people tweeting about Bitcoin reaching xxx amount, or I'll do something stupid scenario.
To be honest , here's what we need to get rid of for Bitcoin to truly be taken seriously by normal people and become the global currency :
1) An end to crazy influencers like you've mentioned
2) An end to scams that make the news ( further making normal people to question Bitcoin )
3) An end to the meme culture where, once again , normal people see these "moon" memes and others and just think of Bitcoin as a joke
4) An end to crypto infighting - an example is the Eth crowd and Bitcoin maxis constantly going at each other on Twitter etc - this hurts crypto in general. I'm not saying don't debate technology - thats important , but when its meme vs meme , its a joke...
Yeah you can't end that. As much as I would hate to say this, haters (or those that take advantage of it) exist because we, enthusiasts exist. If you want them to completely disappear, then the entire community has to go together with it. Nothing we can do about that.
