I play because lack of money atm, but I don't like them. Too many players, too long play till get into money, and it's very little money. I don't recommend play only freerolls because it's easy to take bad habits and easy get tilted because of many donks and bad beats.
My experience, it's hard in late phase of tourney to get into big prizes, because you need to play with more hands to get more chips faster. More bluffing
I can get relatively easy into money (few cents), but it's hard for me to go for top prize aka first 20 places let's say.
I play tight and aggressive when I hit, but it's not enough in late phases. I don't know how else I should play..
