The problem with Grin is the built in Inflation, which defeats the entire purpose of a decentralized crypto currency, and turns a project into
an instant joke. Already there has been a fork to remove this fatal flaw in this project, this Crypto (and anything with money like properties)
can only become viable once it eliminates its inflationary problems...
Grin occupy the decent marketcap in short period so we should not blame the problem of this project. Some peoples are like to participate in this project But long term and short term investment are little risky. So I am not recommend with anyone.
