Actually, it's not cheating, maybe this is some kind of supercomputer used to mine Bitcoin so @tjtonmoy can assume that mining which is usually completed up to 100 years can be cut to 10-20 years with just a supercomputer.
Bruh, mining does work like that !
If next week we double the hashrate the only result will be the cut from 14 days to 7 days, to keep going on like this we need that in every two weeks intervals to add enough power to double the hash rate, and y
ou have to do it every single time because otherwise even if you add four times it doesn't work to that result!
You have scenarios A,B,C:
A is little hashrate added or substracted for for weeks
- 14 days , 14 days and one hour, 13 days and 23 hours, 14 days and 2 hours ~ 56 days
B is doubling the hash rate every two weeks to a total of x16
- 7 days, 7 days , 7 days, 7 days
~ 28 daysC is doubling, not doing a thing, quadrupling, doubling to a total x16
- 7 days, 14 days, 3 days and a half , 7 days, ~ surprise is
~ 31.5 daysFor mining to be done in 20 years instead of 100 years you would need to raise the hashrate
every two weeks interval by a factor of 5. For it to be done in 10 years you would need to increase it EVERY two weeks by 10x.
If you increase the hashrate every two weeks by ten you have 1,4 days every single time instead of 14 days, so 2.8 days instead of 28 days.
If you increase it by 100 but the next period you don't do it then you have 14 days and 3 hours instead of 28 days.
Despite the same hash rate in the end you have a difference of 80% effectiveness.
Now, I hope I don't have to also paint the power needed to achieve x10 every week, which would end up needing the sun to power it up.
