Using your old phones, new phones, laptops, or any other brand new CPU is wasting your time.
Prompting people waste their time, power and money like this is pure negligence.
Do you wanna bet? So, do you think no one ever will mine a block with CPU or smaller devices like Nerdminer in next 10 years? I will be here at 08.01.2034.
The ONLY was a
BTC block can be mined by CPU/GPU or toys like the nerdminer is if difficulty plummets back to where it was around 2013. That ain't gonna happen unless the value of
BTC collapses.
To have even a remote chance of finding a block means the miner must process at least 1 share before someone else finds a block. In other words it has to be faster than 1 share every 10 min (on average). At current diff that just is not going to happen. Period.
I understand the science behind what you mean. Currently on Public Pool, Nerdminer + cpuminer have 3.5 GH/s. It is "Chance per day: 1 in 909,668,533" according to SoloChance. Ten years is 3650 days. So my chance is 1/250k.
Is this calculation correct?
It won't be happen, most likely. But I would bet on it with fair ratios just to have fun.
