The price of tokens not grow. It falls. Team of Suretly continue to develop a project but price of tokens falls. It happenes because of the fall of cryptocurrency market and because people prefer to use fiat on Suretly platform but not SUR token.
The main activity of Suretly is in Russia, but cryptocurrency is not requlated in Russia, that is why there is no demand in tokens.
That people more active use SUR tokens it is necessary to add more listings that it will be more simple to buy and sell SUR.
