I think the number of mining coins needs to decrease, which is not in favor for me as a miner but the growth of these markets has exploded at such a rate than it will take a long time for enough miners to up the difficulty and bring the profits back down to earth, and all that electric and heat output is just plain scary. I don't mind it since it's warming up rooms in the winter but we can' keep this mining fiasco up forever. Lets enjoy the mining for maybe 2 more years as we hopefully watch the majority of shitcoins die and leave only the few and solid POW coins to survive, let the block reward reductions over time regulate these few coins from over expanding.
Anyway, I would discuss what coins should die and survive but that is not for this subforum
