# Mining License

Mining Licenses is a necessary prop to participate in the **BTC** mining, which comes from the staking in **Master Pools**. There are 3 types of Mining License, **NT-L1, NT-L2, NT-L3**, which is produced in different Master Pools.

### **How to get it?**

The Mining License comes from the staking in Master Pools, **which is produced from 0:00 to 8:00 SGT per day.** The more NT+USDT staked, the more Mining License produced.

**Any uncollected Mining License will be burned at  24:00 SGT on the same day, so remember to collect them with KEY in time.**

All mining licenses can be traded freely, and you can also buy special props in the NT-L shop.
