This project is an investment project and I did not find much information about ZrCoin on the web, so in this review I decided to look at the price of this currency. In investment projects, it is very important that the currency price of that network works well, and when a currency has a sharp fall, it is of no use, no matter what percentage of the profit is given to that money.
Well, the truth is that the price of ZRC has not dropped much since July 2017, and it is moving in a price range, sometimes rising and sometimes falling. So I do not think investing in this project is a high risk.
