it is not possible to directly send Bitcoin from PayPal to a blockchain wallet. PayPal does not support Bitcoin or other cryptocurrencies as a withdrawal option. However, you can use a third-party service to exchange your PayPal funds for Bitcoin, and then send the Bitcoin to your blockchain wallet.
One possible way to do this is to use a peer-to-peer marketplace such as LocalBitcoins or Paxful to buy Bitcoin with your PayPal funds, and then transfer the Bitcoin to your blockchain wallet. Keep in mind that using a peer-to-peer marketplace may come with additional fees and risks, so be sure to do your own research and assess the risks before using any such service.
Another option is to use a cryptocurrency exchange that accepts PayPal as a payment method to buy Bitcoin, and then withdraw the Bitcoin to your blockchain wallet. However, as of my knowledge cutoff date, there are few exchanges that support both PayPal and Bitcoin, so you may need to use a third-party service to exchange your PayPal funds for Bitcoin first.
Again, it is important to be aware of the fees, risks, and limitations of using any third-party service to exchange your PayPal funds for Bitcoin, and to do your own research before proceeding.
