This is social media we are talking about, you can see a lot of abuse on using it and don't be surprised that some of those attacking Bitcoin openly are secret investors in which some don't know, it happens that some people have only chosen to be attackers, thereby creating scenes online to get noticed, so that in doing such, they can cause a FUD and FOMO to the extent that it affects the market to fall or rise and they achieve their own goals of selling or buying wherever the market react in such direction.
One take away is that they have been so many people who have fud bitcoin in the past and we have had many of them pivot to bitcoin as investors with long term holding strategy that’s one way to actually silence critics. Michael Saylor was once a critic but now a strong with believe that there is nothing better than it. I think this is how most of them will pivot to bitcoin.
As for those that you said are still spreading fud just to bring it price down, that is the dumpiest thing to do in my opinion, I think bitcoin has gotten to the point where the best way to fud it is to simply be quiet because fudding now is like actually trying to spread the word of bitcoin, once you fud they simply counter your argument I can saw the Peter Schiff post about selling bitcoin for silver and someone immediately called him out that once he says anything about bitcoin, bitcoin does the opposite. He is even called the Inverse Schiff.
Also bitcoin is very well above the level now where fuds can change the market sentiment of it now, bitcoin stood strong during the bangs of war and it is critics that can change that now? They might be dilussional
