Has anyone made a tool to correctly calculate the estimated time based on GPU computing power per puzzle? I could tell without any calculations that we are just scratching the surface using our systems, meaning it's not worth the time and effort, unless there was more bitcoins. Lol.
Easy way to calculate:
Take your speed in MKey/s. Divide range total by your MKey/s.
So if you have 30 MKey/s:
#66 has 36,893,488,147,419,103,232 total keys to check
36,893,488,147,419,103,232 30,000,000 (your total speed) = 1,229,782,938,247 seconds = 20,496,382,304 minutes = 341,606,371 hours = 14,233,598 days = 38,996 years to check all keys in #66 range.
