if you were sitting tinkering in your garage and came up with a way to mine that was instantly 100-1000x more powerful, what would you do?
would you sell it? 51% the shit out of the blockchain to reshape it how you wanted it? hand the design over in a benevolent manner to everyone? drip feed it onto the market to stop insane distortions?
Imo the best solution would be to report it to the devs, because if you have found a way to mine 100-1000 times more faster, than sooner or later someone will find it too and in the end someone will use it with malicious intent. This will result in a huge crash and maybe even fork, so it can only be profitable in a short term. It's possible that the panic will start almost immediately after everyone spot a new powerful miner. In the end, a lot of people will be angry so the person who did it will have a huge target on their back for the rest of their life. So it's better to just mine a few dozens of bitcoins and report it to the devs.
