So far, we do not see an ideal currency as a means of payment. All currently existing means of payment has both its advantages and disadvantages. So there is no need to try to drop something. The existence and use of cryptocurrency depends on the availability of certain technical means, certain knowledge and skills, the Internet and a number of other technical issues. In cryptocurrency, we sometimes make mistakes, we are attacked by hackers and scammers, it is very volatile, its price depends on news factors. Therefore, do not rush. Cryptocurrency is still in the process of improvement and development. The future is money or not, time will tell.
