This is a huge point I'm still trying to understand about cryptocurrency as a whole. Will transaction fees be enough to keep miners going on any coin. The rationale is that once all the coins are minted, there will be more in circulation and thus more transactions and more tx fees. Those fees are supposed to subsidize the miners. The crazy thing that will probably happen with bitcoin is that towards the end, there will probably be huge hashes fighting for the last coins. That will push up the difficulty and then they will probably fall off when those last coins are minted, I think, leaving the difficulty stuck too high for a while. That is a ways off though, so maybe something will be done about that, or there already has been something done and I just haven't heard about it or haven't understood it fully.

But with the case of this coin. If all were minted in 2 weeks, there wouldn't be many services set up for people to spend their coins at, so there would be minimal transaction fees and hardly any incentive to mine at all.
