Mine was a lending coin because I was already into many HYIPs and lending projects. So I thought the only way to make quick bitcoin was to lending coins and quickly make money. It was a bad lesson. I should have stick only to existing project, all these madness was in 2017.
How big profit that you will get from the lending site depends on how much your annual yield. FYI so many people were also getting scammed by HYIP and lending site too.
The biggest profit still came from the ICO. I have ever gotten a bunch of money from my first ico too.
