# Bitcoin ($BTC)
**LiaBTC** is a rebasing tokens for aBTC.
aBTC is designed to have the same value as Bitcoin, maintaining a 1:1 ratio (1 aBTC = 1 BTC). It's created on the Stacks platform, which enables smart contracts and apps for Bitcoin, thereby aiming to expand the utility of Bitcoin within decentralized finance (DeFi).
## 1 LiaBTC = 1 aBTC
LiaBTC rebasing mechanism is similar to other LISA rebasing token mechanism.
### How Long to Stake In and Out?
You can stake your BTC to LiaBTC immediately; however, to unstake, you would need to wait 1,000 Bitcoin blocks for your LiaBTC to be converted back to BTC.
* **Stake In:** Immediate
* **Stake Out:** 1,000 Bitcoin blocks
