A Discord marketplace!

Description

I got a lot of items to sell so buy buy buy.

Solution

There was an "auction bot" on Discord.

It sold different types of items (single, collectable, part and set). The value of a single item is static, a collectable item increases in value by an arbitrary multiplier when sold, and parts can be combined to form a set which is worth more than the sum of its parts!

To view the items being sold, we can use /marketplace. The goal is to get enough money to buy all three flags (Flag Common, Flag Rare and Flag Ultra Rare).

We start off with $10,000. While there are many paths to winning, my strategy ended up being repeatedly buying and selling the Shiny Pokemon Card item.

The first Shiny Pokemon Card was bought for $10,000, but when sold, it made an overall profit of $5000.

As our balance increases, we could buy and sell more items at a time, increasing the rate at which we earn more profit.

Repeat this enough times, and we get enough money for all three flags.

Use /redeem_flags, and the bot DMs us the flag!
