# Exchange
The official **CryptoMines Reborn Exchange** was developed internally so that players can find it within the same website of the game and ensures the safety of all our players when exchanging their **CRUX** to **WCRUX** or vice-versa.
Remember to make these exchanges through official and secure means as it is the responsibility of each user to keep their account and tokens safe. CryptoMines Reborn is **not** responsible.
You can access our exchanges through the following link:

### Limitations
* If your tax is 0%, when exchanging $CRUX to WCRUX you will set a sales tax of 75% when trying to sell WCRUX to $CRUX. Otherwise, your timer will keep going down.
* A timer for your early claim tax is set at 75% and decreases by 5% daily once you sell **WCRUX to $CRUX.**
* Once you change your **Dark Matter** to **WCRUX** your early claim tax will be set at 25% and decreases by 5% daily.
* Claiming the vault from the Marketplace at 0% tax will set it back to 75%.
