BTC trading is now available on Ethereum blockchainWBTC (Wrapped Bitcoin) was officially launched on Ethereum as a BTC-backer ERC20 token and is now available for trading on several applications and platforms. WBTC was first announced on October 26, 2018 as a joint initiative by BitGo, Kyber Network, Ren (formerly Republic Protocol), and other community partners, to bring Bitcoin’s liquidity to the decentralized ecosystem on Ethereum and enhance all decentralized applications (DApps).
WBTC standardizes bitcoin to the ERC20 format, so DApps such as Compound, Dharma, dYdx, Gnosis, Maker, Set protocol and more can leverage BTC for decentralized lending, margin trading and derivative markets. Further compelling new applications and use cases will be identified, explored and implemented as the ecosystem continues to grow and actively innovate.
By bringing Bitcoin’s liquidity to Ethereum, WBTC also makes it possible for traders to use Bitcoin value for token trades on decentralized exchanges (DEXs) such as AirSwap, DDEX, ETHfinex, IDEX, KyberSwap, Loopring, Radar Relay, RenEx, Switcheo Network, TheOcean.
Eight initial merchants will be facilitating conversion between WBTC and BTC: AirSwap, Dharma, ETHfinex, GOPAX, Kyber Network, Prycto, Ren, and Set Protocol.

This sounds like some bullshit, I'll have to look further into it. Sounds like some IOUs for Bitcoin.
