What a nice topic!
As far as I'm concerned, the future of cryptocurrency is very bright. This is due to the fact that many nations around the world are now adopting the blockchain technology. The more we have good and functioning projects on the blockchain having real-life applications, the better the blockchain would become. One of such projects that I have known of is VEIL.
VEIL is a project that has good use cases for its coin because its real-life application drives the demand for its coin and this will surely go a long way in giving positivity to the coin value, and investors on the blockchain would always be happy on their ROI.
