It is deeply saddening that using #BTC on #ETH requires trusting a custodianship with my private key. There is no way around that.
However the fact that 0xBTC exists at least gives us a tool that accomplishes the same effect trustlessly, albeit with lower liquidity.
Anyone can deploy a standard token tied to a centralized platform. Centralized platforms will come and go. They will live and die. Browsers, exchanges, apps.
The secret to #0xBTC is: there is no central platform.
