Come on, let's get real. I myself computed that if I had 150k $ lying around I would have solved 130 in less than 90 days. Simple crude math - divide total ops by number of op/s, again by ops/GPU/s, multiply with price/h.

So no supercomputer required here, just $ to pay for the most optimized piece of software to run, to minimize costs.

But now 135 requires 5 times more money to solve, or for GPU prices to go down, or for performance per $ to go up, which WILL happen. What I do not understand, is what the deal is with the 3Emi script address, is it a group, is it some sort of smart contract, why was it not spent already, etc.
