There is nothing surprising in this, everyone has the right to their opinion. You do not need to listen to anyone and make a decision based on these comments. Bitcoin has many functions, and it is already accepted as a means of payment, so, bitcoin - the future.
I agree, we all have our own point of view it only depends on each one of us what we're going to believe to. It is hard to tell which is true and not because there are a lot of fake news about bitcoin, trying to bring bitcoin down because bitcoin is a threat for them and seeing bitcoin succeed in all kind of fields is not good for them. Bitcoin is meeting its function to its community it depends on the user how he/she is going to use it.
