WBTC (Wrapped Bitcoin) added 15,000 tokens (approx. $165 million) 24 hours after UNI token launch, taking the amount Bitcoin locked in DeFi to $1.2 billion. High returns on Bitcoin-specific pools is another impetus for the mass move. The WBTC-ETH pool on Uniswap has become a significant source of attraction as it is one of four pools on Uniswap with added UNI token incentives. Currently, the WBTC-ETH pool is the largest pool on Uniswap in total liquidity at $391 million. This amounts to a staggering 900% increase since Sept. 17. The relative volume of other WBTC pools on Uniswap paints a clear picture of the source of the demand.
