I dont know that you could port Bitcoin onto Grin. So it is a threat.
But their monetary policy is fuxxed. Big mistake having an endless emissions. Same trap Monero fell into.
So that significantly reduces the threat.
MW can be implemented on a second layer or as a sidechain with BTC I believe.
So, how many grins will ever be made?
Currently set to 50 per 60 seconds (it was going to be 60/m, but I think they finalised at 50/m). That is not designed to change. So it's infinite.
Well, if it's infinite it won't be worth anything. That's Economics 101.
That would be my understanding too, which has killed a lot interest that I initially had for it. However, how many other coins are like this? and how many of those have gone from low value to a high value.
Monero? But isn't their supply cut down to only 0.3 every block at some point?
Even with open ended supply it still seems that a lot of money can be made in the medium-term even if long-term it is destined for disaster.
50 every minute forever seems like a awful lot though.
