Bitcoin is still new and has a smaller market cap than other investments that one famous person on Twitter can influence the prices of Bitcoin and other cryptocurrencies.
This is partly the truth, his quite an influencer but the pandemic has made people to be online more than usual and with a few retweets of what Elon tweets about gets people excited and for all we know word travels faster on these online channels.
I am not a huge fan of Musk manipulating the market for his benefit but i am not in favor of banning him from Twitter solely because of that, if he is conveying fake news then then Twitter will tag him as manipulated news and till now Musk is smart enough to avoid these tags because he is just voicing his opinion and you cannot ban someone for just voicing his opinion.
I would like this to happen but fact of the matter is Musk has both feet dipped in cold and hot water such that at times he creates a bullish atmosphere for crypto which we all love but when he means to be bearish this is the part about him that we all hate him for..
