Discussion about forum gold coins

First of all, what I want to say is that I would like to thank "Xiaoqian", "Netname" and others for their contributions to the forum! I briefly looked at these three plans and found that there are problems, but I think it is necessary to show them to everyone. I am solely responsible for the following three solutions, so you don't have to worry (yusui@小dian55555).
As for the issue of forum gold coins, everyone has been debating it for a long time. I think it is time to put forward these three plans.
Plan 1:
A. This plan is the most humane plan. First of all, no one on the forum has zero gold coins, no matter how many. The forum has opened a new function, the function of purchasing rare medals. Of course, you can design any novel new medal, as long as it is "rare".
B. The number of "rare" should be consistent with the number of rich people on the forum. For example, if there are 6 members on the forum with a total gold coin of more than 100 billion (including 100 billion), then 5 medals will be sold for 100 billion. Moreover, the color of the medal should be as strong as possible, the more conspicuous the better, the shape should be as unique as possible, and it should have a "rare" look.
C. Classify the above-mentioned 6 people as first-class rich people, and stipulate the 5 medals as first-class medals. If there are 7 more people whose total gold coins are from 50 billion (including 50 billion) to 100 billion (excluding 100 billion), they will be classified as second-level rich people. Then continue to sell 12 more (6+7-1) second-level medals (the reason why there are 12 medals, 6 of which are to provide part of them to the first-level rich people, to prevent them from being too worried about money and unwilling to spend 100 billion at a time to buy first-level medals). The second-level medals are sold for 50 billion. If there are 8 people whose total gold coins are from 30 billion (including 30 billion) to 50 billion (excluding 50 billion), they will be classified as third-level rich people. Then continue to sell 20 more (6+7+8-1) third-level medals, and the third-level medals are priced at 30 billion. Only one medal of the same level can be purchased! (To prevent bored rich people of a first level from buying multiple medals, causing an imbalance in the number of medals of the corresponding level)
D. Of course, the above solution is rigid, and the following method can also be adopted. Only members whose total gold coins are equal to or exceed 100 billion can purchase first-level medals, and only one medal of the same level can be purchased! The price is total gold coins × 90%. Only members whose total gold coins are equal to or exceed 50 billion but less than 100 billion have the right to purchase second-level medals. Even rich people with hundreds of billions do not have the power. The price is 90% of the total gold coins. Only members whose total gold coins are equal to or greater than 20 billion but less than 50 billion have the right to purchase third-level medals, and the price is 90% of the total gold coins. The number of medals is the same as above!
E. As for the sales time, they are always on sale, but the number of medals is updated every Monday. For example, this week the number of hundred billionaires changes from 6 to 2, then the number of first-level medals will be changed from 5 to 1 next Monday, until there are no more 100 billionaires or 10 billionaires. Cycle like this.
F. When most people's gold coins are reduced, the limited price of rare medals and the limited purchasing power will be further reasonably modified. As for the specific number of medals, it is selected based on the number of people in the forum with different gold coin levels, the same as above.
Option 2:
Bank deposits charge interest instead of interest. The interest is arranged by the webmaster.
Option 3:
The gold coins are cleared to 0, the level is cleared to 0, use gold coins to purchase levels, and the levels can only be purchased from low level to high level. High levels cannot be purchased directly. You have to buy them level by level! Cancel the "level depends on the number of gold coins" setting, because most people save money and the level keeps changing, so the level loses its meaning. As for the price, it only needs to increase linearly. For example, the first level is 10,000 gold, the second level is 50,000 gold, the third level is 100,000 gold, the fourth level is 500,000 gold, etc., and so on.
This is my plan, for reference only, I hope you will choose it. Also, will the webmaster design medals? Does the forum system have such configurability? It depends on the webmaster.
