Import a paper wallet into Blockchain.info
You have created a Blockchain.info wallet so login and continue to transfer the funds from your paper wallet.
To import your paper wallet go to the settings menu and select addresses. Then click on import address and enter your private key. The private key will be validated and the funds from your paper wallet will be transferred to the Blockchain.info wallet. If you want to send coins from your Blockchain wallet right away, use priority fee, otherwise you might have to wait a couple or hours.
Please note: Normally never enter your private key on any website! However blockchain.info is well-known and established, and their website is set up in such a way that your private keys are not sent to their servers. However for larger amount of bitcoins and / or long term storage I would advise to use a local hardware or software wallet.
Congratulations, you have now transferred the bitcoins to your Blockchain.info wallet.
You can leave your bitcoins there and use them once in a while or you could sell your bitcoins on Bitonic
