I sold some art in the market place. I went to bit address.com and set up an address, had the BTC sent there and I printed out the sheet of paper with the address and private key.
Now what?
Is this all i need to do for long term cold storage?
That sheet of paper is your paper wallet, and you will only be able to spend your bitcoin with the private key.
So, you should to store it in a secure place and don't show the private key to others.
I was going to send some to my Blockchain wallet, how do I do that?
You need to scan your qr-code, or type the private key to import it.
