I think the price instability of cryptocurrency is one of the main reasons, and the encrypted wallet is easy to be attacked by hackers!

I think one of the problems making cryptocurrencies being not successful as a medium of payment at the moment is Blockchain Trilemma. Blockchain is still low. The capabilities to scale up of Blockchain is still being questioned. How can a new medium of payment work effectively if its TPS is under 100?

The global economy is nearly 80 trillion USD per year.  Payments using any type of cryptocurrency as a medium of payment is a tiny fraction of this total.

What are some of the reasons preventing cryptocurrency from being more successful as a medium of payment?

I believe that cryptocurrencies are gradually finding their wide distribution, they are recognized by various states and financial organizations. But while they are not actively used, because many people do not understand the possibilities and advantages of cryptocurrency for profitable transactions.

maybe what you say is like what happened in my country, the government has not fully formalized the crypto currency as the prevailing currency and of course the government prohibits transactions directly with crypto currencies and currently it cannot be a medium of payment

The stability of cryptocurrency prices is very bad, extremely vulnerable to whale control, and the security of cryptocurrencies is also a hidden danger, because hackers are everywhere!

Because right now the cryptocurrency is still not mass adopted. And some of the people still uses physical cash as their mode of payment. But I am happy for the progress of the crypto in payments. Because many projects right now are the main idea as using their crypto as a mode of payment and successfully implemented it in selected places.
