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.
I don't really understand the comparison between freeroll and poker, I know that all the games has benefits depending on the one you how to play, because what makes people to win some games constantly it's because they have learnt very well, so I believe that when you know it well you will benefit from it, some persons don't know poker game but they learnt very well, but that will not give them assurance that they can make profit, so what I'm saying in essence is that even this freerolls of bet, if you understand it, you will make out something good.
