# TOKENOMICS
Crypto-Bike uses the MTCB token on BSC chain. \
We have developed some mechanisms to maintain buyer interest in our token and contribute to the overall development of the project's economy:
* To play, users must purchase NFTs;
* NFTs can be upgraded, which increases the user's rank. This upgrade requires items that can be purchased in our marketplace. The higher the NFT rank, the more valuable it becomes, increasing its attractiveness to users and boosting demand for the MTCB token;
* Purchases of upgrades for items;
* Service fees for participation in tournaments;
* Fees for users in the marketplace.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://crypto-bike.gitbook.io/crypto-bike.game/token/tokenomics.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
