You mean better than cryptocurrency?
I think it is possible, or maybe cryptocurrency becomes even more. Cryptocurrency can still improve and we all know that.
We cant still see its maximum capability and we all know that cryptocurrency is still a child, waiting for a great developer to make an improvement in the crypto world.
Yes, maybe crypto will be at its best in the future with extensive utilities. At that time, I was sure the majority of the world community had used Cryptocurrency. I am still waiting for this to come true. When crypto is already used by the majority, then maybe there will be new technology that is more advanced.
