First of all, the cryptocurrency must be known to more people. Secondly, the national government needs to be recognized, which will speed up the promotion and growth of cryptocurrency. I hope to arrive sooner.
It needs to be regulated by the government first before it becomes a legal tender of payment. As a medium of payment, some people are already using it including me when I wanted to pay my bills because we have a platform wherein we can pay our bills using cryptocurrencies so it makes it easier for the crypto users in our country to do such thing. The scope of being a successful medium of payment may be small for now but later on, it would become larger.
