Yesterday's World Cup gameplay, many friends said there are too many coins to trade, is it okay to just play one? I thought about it and updated an idea, let's discuss it. Every transaction over 100u is counted as valid, and each transaction gets a lottery ticket. It's not purely based on trading volume; if it were, the big players would take too much. Of course, we could also only give tickets for buy transactions, not for sell transactions. After the transaction, there will be a hash value, which is a combination of letters and numbers, a total of 36^2 types, divided by 48 teams, equals 27. This means if the last two digits of the hash value represent a certain team, then the probability for all teams is equal. Then 01-27 represents country A, 28-54 represents country B, 55-81 represents country C, 82-00, plus 0a-0h represents country D, and so on. Then a portion of the transaction fees goes into an instant prize pool; for example, if the fees reach 1000u, we draw 5 prizes of 100 each. All transactions that meet the criteria can enter the lottery, and the method is still based on comparing hash values. For instance, the hash value of the first 10,000 qualifying transactions serves as the standard, and the previous 9999 transactions can also enter the draw, with all hash values' last digits corresponding to more winners. Then the group stage, 1/8, 1/4, semi-finals, and finals each correspond to a portion of the prize pool. This part corresponds to the countries being favored, or we could draw a grand prize from among them; I feel both options are fine. Some ideas for everyone to discuss.
