I choose WBTC. Because in my opinion this is a project to help BTC holders participate in the DeFi market easily and quickly. Because it is an ERC20 token, WBTC is transferred faster than regular Bitcoin, but the main advantage of WBTC is being able to integrate into the world of wallets, dapps, and smart contracts on the Ethereum network. Never before has an investment in BTC been so flexible in the crypto market, BTC investors will be able to make more profits thanks to the WBTC.
