Revain is an interesting yet useful app for someone, such as myself, that is a novice in the crypto world. I am learning a lot of little things through others reviews, as well as getting a broader understanding of different types of cryptocurrencies. One always has to remember while reviews are honest, they can be subjective. But so far I'm learning about new tools at my disposal. I'm just starting out so the plethora of knowledge is mildly overwhelming. But I think I'll get the hang of this. One plus side of the app is learning about the actual functionality of the decentralized system, and what each of the various coins are designed to do. This is more than just buying, trading and holding coins. It a complicated system with so much to learn.
