Am I correct in stating that there will be approximately 315 million GRIN after 10 years?
1 per second x 10 years?
If so the supply doesn't seem that high to me considering what the potential is for this coin to develop in the next ten years.
You're right. I also think the same - many people misunderstand. They think that Grin's monetary policy is stupid and irrational. Well, it is not. It has been designed this way on purpose. I personally think it's a good model and will play out nicely. Here's a nice chart that shows the Grin supply

However, the implementation was more for the adapative block size than the distribution, but it still gives continuous incentives for miners.
In anycase, a hard cap on the supply in some coins are not practical unless the developers were planning something else for the coin other than make it a
daily currency. The hard cap encourages
hoarding, which might be a limitation for mass adoption.
