If I have good amount of coins then I check after every one hours to ensure that my bitcoins are safe and intact as there are many scammers around and checking balance gives great level of satisfaction.
well you wouldnt have to do anything about it, if your coins werent safe and if a hacker managed to get to your wallet then all your bitcoins would be just stolen in my opinion irreversibly
i check my bitcoin wallet a few times a day if i have some money because i like to see the value of it fluctuating all the time and me making some more dollars out of my savings
