Well we always have two sides of a story, always! For bitcoin, it is either a believer or a non-believer! So there you have it! Non-believers like Jemie Dimon or Warren Buffet will always speak against bitcoin and believes like Elon Musk will always speak in support of bitcoin.
That argument will continue and non-believers will always find ways to bring bitcoin's reputation. The bitcoin market initially used to react to such comments and views but it's now long gone! So the argument will continue while the bitcoin will also continue to flourish!
