Lets say I have 8 equal devices.
If my goal is to use 1/8 of my work as a "lottery entry" in trying to find a block solo mining, is there a difference between the following 2 scenarios?
scenario 1) running 1 of these devices on solo pool full time and the other 7 on a regular pool full time
scenario 2) running all 8 of these devices for 1/8 time on solo pool and 7/8 time on a regular pool
or put another way, is there any difference between a low hashrate over a longer amount of time or a proportionally higher hashrate over a proportionally shorter amount of time when solo mining?
