It is always worth investing time playing freerolls because the only thing you are going to invest is time and most of the freerolls are turbocharged, but I tell you something that happened to me years ago: one day I decided to play a tournament in pokerstars, I remember that the buy In it was $ 0.55, I spent a large part of the tournament in 1st place, after more than 8 hours playing I was eliminated, I do not remember well from which place I was eliminated, but it was something like top 100, and I only received $ 5 after being 8 hours playing, which tournament do you think was worth playing? Perhaps the investment of money was very low, but the time I invested playing was a lot, from that day on I better analyze what I was going to play in terms of investment of time
