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?
The market can not be predicted, but I do not think the bitcoin value can fall to zero. This can happen if its use is banned or there is a competitive currency. This is not possible, as everyone expects an increase in the price of it. We are optimistic about the future of bitcoin
