3yrs long time wow. I guess it's a bit like playing a free lottery.
Except that the lottery isn't free, you pay per second (mostly electricity). And the chance of winning is practically zero.
Why don't you start by guessing my creditcard number and phone number? It's much more likely!
It's easier to get jackpot on lottery though. For example, jackpot odds on Powerball is 1:292.201.338 or approximately 1:2^28.12.
Even without buying a ticket, the chances of winning after finding someone's lost ticket are still larger than the chance of finding a funded Bitcoin address.
