Currency failure generally occurs due to the type of hyperinflation, and there is always the potential for technical failure, currency competition, political issues and so on. As the main basic rule, there is no currency that can be considered very safe from failure and difficult times. so is it possible that bitcoin can become worthless?
I believe that the only time something should be considered as worthless is when it has no value. Bitcoin has good value, and if you check the value in the last ten years, you will see that the value now is very much bigger than what it was back then. So anyone who is saying that Bitcoin is worthless is making a very big mistake and they say that because they dont understand a thing about Cryptocurrency.
