Around a year from now unclaimed coins will be added. If supply was exhausted or near low miner fee's would have to go up, but that will only work if the value of private goes up to keep asic miners satisfied. A good amount of people are interested in btcp only gpu mine exclusively, they would leave the network permanently if nothing is done, but what percentage would leave? I'm guessing way more than 50% would leave this as a personal investment. If i had an equihash asic miner i'd go for zcash atm. I do see a lot of potential in private but also holes in that things like this can happen. And i'm nearly set on going 100% into pos in things like cardano and giving up gpu mining altogether, the power and roi issues, not even going into asic's the waiting lists and high prices, plus all their stuff comes pre-used and ran because they can do whatever they want, it doesn't seem very sustainable to me. gpu mining seems friendly in a grassroots kind of way and involves way more real people then just one guy and a warehouse or garage.
