Hello, I am new to Ethereum and I am not that literate in a lot of what is going on. I used myetherwallet.com to generate a paper wallet. I then printed it, and used shapeshift to purchase exchange some Bitcoin for Ethereum. It seems the transfer was successful but when I enter the public address to check the balance of my new wallet on xbalances.com the address is not found. When I enter the address on Ethereum.org I get a message reading "invalid Bitcoin address". I went back to myetherwallet.com and used the "view wallet details" feature. This had me enter my private key which I thought was not very secure and then said my wallet was "registered" or something to that effect and I did see a balance but also saw that the private key was unencrypted which made me think I had then compromised the security of my paper wallet. Etherchain.org did recognize my address and provide a balance however. I am using an iPhone 6 and a Mac with Chrome. If I am posting in a more advanced forum please excuse me, I do not wish to clutter up the discussion. Please just point me in the right direction. I would just like to know why my address is not being found, and if I need to create another wallet and transfer the balance since I entered my private key unencrypted. Thank you for any help.
