Since 2021,
@Stacks has paid out 4,200+ BTC through PoX.
Now, with PoX-5 the payout system will work for BTC staking without asking Bitcoin to leave L1:
🔹 BTC stays locked on Bitcoin
🔸 STX backs the staking capacity
🔹 PoX miners fund the BTC rewards
More BTC looking for yield = more STX needed to support the staking side.
