Revain is a platform for sharing your experience about a particular another platform in which you have used and in which revain support as a topic. Revain support many exchanges, crypto projects, payment system and many more. I didn't know that such platform is existing not until a friend introduced me to revain, because he knew I am very good at sharing my experience. Seriously, I was not really interested in RVN I get for each review I write, my aim was to share idea and keep o. Making more research. Well, revain had been the best review site I have ever come across. I have not really noticed any big problem about the platform.
