Without bitcoin, there would be no cryptocurrency. Bitcoin came first and used as basis of other cryptocurrency, thus, calling it the father of cryptocurrency. It is the first cryptocurrency that gave benefit to people since this acts as a big source of income. When it comes to currency, bitcoin is much better since it is decentralized. If any other cryptocurrency may able beat bitcoin according to its value, I think, it will be less special then.
When something or someone is popular, it must have some reasons and the same case can be applied here for bitcoin. The popularity of bitcoin is only due to its benefits and properties. In the present time bitcoin is the best currency and is better than all of the other digital currencies.
People tend to use bitcoin for online payments and procedures rather than any other currency because bitcoin is the best in all of them.
