In theory this sounds good, but do you really think GPU miners will stick around if they are losing money? For example, if ASIC miners came in and increased network hash rates by 200%, don't you think that the GPU miners would leave equihash, effectively reducing our predictions of difficulty increases?
Great point. One that didn't cross my mind. Plus the fact that the crypto market may rebound, increasing profitability, may just justify getting a mini for $850 at this point in time...
