I red about GRIN and didn't believe that its price would rise. Because it has a strange mining way. Almost everyday new 100K GRIN coins are mining. So everday market value rise about 500K USD. It is sustainable?
And why its price has just raised so quick?
Supply, circulation and increase in number of transaction only make the coins value in the raise or fall. I am not sure about the GRIN coin explain their protocol and etc. They want to have the best outcome with their project.
They should list their coins in the best exchanges to reach the good supply and circulation.
