I'm considering solomining with my full 12 Thps when it comes online - save for electricity costs, which would give me a 1% shot per day!!
25 btc / .35 = 71.42 to 1 chance.
the math works this way. either way the power spent is the same so forget the power …..
for a day he spends .35 btc (what he would have earned in a pool)
.35btc = about 217 usd and 25 btc = about 15500 so his chance are no better or worse then pool mining.
and you are correct that 1/72 = 1.39 percent not 1 %
I was thinking the odds would be worse than the actual lottery but when you present it this way it doesn't seem like too far off a probability to hit one
