The answer is quite simple really, it takes 24 hours to be eligable to mint so you can have your pc off for all that time and then turn it back on 24 hours later.
It might not stake exactly on 24hours unless you have a big block but it will not long afterwards.
Every time you stake send all the coins (With Coin Control) to a newly created address in you wallet so that they will all be in 1 Block so it will stake quicker and compound more.
You could also not open your wallet for a few days and get the days you missed out on with that 1 big input that has been waiting to generate for e.g if you stake 1.5 CUBE every day then you would get 4.5 CUBE if you waited to open the wallet every 3 days.
