I purchased ethers from an eBay seller and the seller sent me a public and private key for etherchain.org. I have a Jaxx wallet and was looking to transfer my purchased ethers to it, but I have absolutely no clue how to do that.
The seller said that they don't send to wallets and that everything is available on the public ledger. I can see it on the public ledger but I'd rather have it in my private wallet. I just don't like that we both have the private key.
Any guidance would be much appreciated
