a good player will have both modes.
it completely depends on your stack relative to the players left in the hand.
if you are one of the medium stacks and the players on your left have big stacks and aren't afraid to mix it up, then you need to kind of wait for a premium hand or for the bubble to burst.
if you are one of the big stacks you should apply bubble pressure relentlessly and cheaply. min raise as many hands as you can if your stack can take it and the players at your table are concerned with min cashing. you could literally min raise 100% of hands and just fold everything except QQ+ and AK to jams and print money.
if you are one of the shortest stacks then you have to figure out whether or not you are likely to blind out. eventually when you are low enough your
equity from a min cash becomes the main value of your stack, so you should fold almost everything if you think you could outlast other players without busting. for instance you have only 5bb but there are several players with 5-10bb and there are still 5 tables left....you might actually be able to just blind down and wait it out and essentially you are giving up any chance to win the tourney. but if you have 5bb and everyone else has 12+ bb then they are essentially going to wait YOU out and they will most likely win this game....so you should get it in a reasonable spot where a double can still get you out of trouble.
