I suggest that this time we don't bother with coefficients (let's leave that for the next tournament, after carefully considering everything), but simply place bets, say, on 5 matches at a time, and write our predictions directly in the thread, of course, indicating who we are betting on, since I don't see any point in hiding these predictions. Whoever guesses all the matches correctly wins the entire accumulated pot for the tournament. If no one guesses correctly, the entire prize money goes to the next tournament, and so on. And of course, you need to copy and save all bets for yourself so that no one can change anything afterward, and announce "bets are placed, no more bets are accepted" only after that the tournament begins. As for the timing: 2 days for placing bets and 7 days for the tournament, I don't think that will be a problem for anyone. And at least make 6 minutes for regular templates, and for M200, you can leave it at 4 minutes (or even better, create normal templates and a seasonal timer, or a chess timer).
Naturally, only those who have purchased participation should participate in the betting. Let's say we make a fixed bet per tournament - 50 rubles, i.e., to place a bet on 1 tournament, a person must send you at least 50 rubles or more - so that they don't have to top up after each loss. Ideally, a separate time should be set before the tournament, 1-2 weeks, for buy-ins, all the money collected should be recorded in your accounting, and all calculations should be done in real-time in the first post, so that it is immediately clear who has how much left. That is, it is best to cancel this tournament and start everything from scratch, since only 1 tournament has been played, and with the new rules, I am sure, more people will sign up.
P.S. You should remove your announced prize (50$) for BOB and simply take on some minor expenses to cover the commissions when transferring money from players (where this commission exists). You can also create an FAQ about where and through which system it is best to send money to you to minimize transfer costs.
I would do it so that everything is clearly visible, who is betting on whom, the bet per tournament is fixed, let's say 50 rubles, to participate in the betting you must deposit a minimum amount of 100 rubles (for 2 tournaments), after each tournament, as Namvan described, in case no one guesses all the results of the matches, the prize fund goes to the next tournament, and so on, after 2 tournaments (since the deposit amount is 100 rubles, all participants participate in the second tournament), top-ups begin (and it is logical for them to be present, since the jackpot after 2 tournaments with the participation of, for example, 10 players will already be 1000 rubles). The time for placing bets should be short, draws should be prohibited, only wins or technical wins. The number of tournaments should be fixed before the start of the tournament, for example, 8 or 10 (it depends on various factors). The easiest way to accept money from players is, of course, via a phone number, for example, simply have the organizer deposit money on the phone for participation in the betting, and the organizer, in turn, deposits this money into the tournament. Of course, I understand that the money that will be on the mobile operator's account will not be spent immediately, but in a month or two, but that's what the ORGANIZER is for, to invest, so to speak, in the future and promote Heroism.
And the prize fund, in case of winning, the organizer will have to transfer to a card, for example, Visa (this will require some effort) or to the winner's phone number, for example, at the winner's request.
