Optimism is certainly not wrong, but I do not agree with blind optimism.
This year is because of too many blind optimism, and someone even said that Bitcoin will reach 25,000 US dollars at the end of the year, this is exaggerated predictions without any analysis,  which is irresponsible misleading，this will only make people feel more disappointed after the bad reality.
We certainly need some optimism, but it must be cautiously optimistic.
