3x Stacking Rewards, Trustless Swaps, and 'rounding up' your change into STX & BTC

Bitcoin DeFi keeps getting easier and more rewarding. Trustless swaps made a splash last week, loans that repay themselves are close to launching, and Okcoin is celebrating their new Earn app by making it possible to earn over 30% APY on Stacks holdings, paid in bitcoin. Meanwhile, MiamiCoins (built on Stacks) have been putting the underlying Proof-of-Transfer mechanism to work to generate over $2M for the city of Miami.

It's exciting to see the Stacks Ecosystem continue to play the leading role in enabling DeFi opportunities for Bitcoiners, including NFTs that generate Stacking rewards, training for developers in HK that want to write smart contracts for Bitcoin, and pushing forward a host of updates to developer tooling and the Stacks chain.
