We can not condemn someone for their free thoughts. Maybe the price will be as he says in the future. How do you know? Maybe our thought is wrong. His only mistake is that if there is a community following him, he may be able to influence them. But, as I understand from other thoughts, there are very few who see him as smart. If so, we should not mind.
Yes, we can not condemn someone because of their free thoughts, but there is a limitation in stupidity. This is not his first time doing this, he has done it many times. As an influencer, he should have acted wisely or at least acting just like a normal man and do not spout so much nonsense on the internet like this.
if he does not like Bitcoin then stay away from it.
there is no right and wrong, it is all about choice.
