I don't think freerolls should be taken too seriously. They are simply a free opportunity to have a good time, gain basic poker skills and get another portion of life observations. Freerolls are also a free opportunity to get a small dose of adrenaline. But it is impossible to build a long-term earnings strategy, for example. Poker, in my opinion, is generally a difficult source of income. Even sports betting seems less difficult to me. There is little you can calculate in advance in poker. Yes, you also need a very good memory to count cards.
