Its smarter and more statistically probable if you rent as much hash as possible and run it at once.
More workers working on the same block == greater chance of solving _your_ block in a given amount of time.
If you just space out the hash in smaller amounts over time; you have less hash to find that block in a given time and it is somewhat wasteful.
Wrong! A hash is a hash.
In the same sense that pointing two antminers at two different BTC payout addresses, will both have the same probability of finding a block; whereas if they are both mining to the same address, they stand twice the chance as find a block as when they are working independent.
Wrong!The more hash you cram in that "10 min" gives you a higher actual probability of finding a block.
Wrong! You are not trying to find a hash in
that "10 min", you are trying to find a hash that exceeds the current difficulty, the difficulty is adjusted so that the average time to solve a block is 10 minutes.
1000 Gh/s for 1 hour gives exactly the same chance as 1 Gh/s for 1000 hours (assuming the difficulty stays the same for the duration).
