This coin was discussed few months back here in this forum, there were some thread about it here, that was how I got to know it, even though it doesn't carry so much hype like some other project does, GRT is solid project no doubt, could be more better as development progresses and there are actual usage of the project, as it is, the crash in the market has reduce a lot of good project in price and grt is no exception,
This is worth buying for long term, if everything goes well am sure investors will be satisfied.
