Bitcoin has been criticized by forum users for its market volatility since its inception. Not only Bitcoin, but almost all objects in the world have their good and bad sides. For example, we can say that straight-curved, flat-rough, Humanity-inhumanity, considering all these, it appears that there is no fixed rule that Bitcoin will only rise. However, it is not reasonable to close the investment system if the market is going down. We have to prepare ourselves humanly and manage ourselves to achieve the highest ATH of Bitcoin in the future, then we will be able to enjoy the potential light shower of a big future.
You don't have to pay attention to these critics because some of them are just there to create FUD. They have predicted that Bitcoin will die several times but it has not pass. Some of them have begun to change their views while others want to remain sceptics forever. Just have a plan for your Bitcoin portfolio and stick to it regardless of the pressures.
I guess you can't blame them because it’s normal for some people who lack knowledge to criticize Bitcoin, but over time, it has been proven that Bitcoin isn’t a Ponzi scheme, as some initially believed. what they lack is proper education, but if they take the time to educate themselves for the right reasons, they’ll eventually appreciate Bitcoin’s value and its potential to replace gold in the future.
You have to blame them because you don't criticize why you don't know. It is your responsibility to read about a concept and understand it before you take a stand. Some people depend on hearsay and a not receptive to change or innovation.
