Thanks for sharing. This was something i did not knew. I am currently using exchange wallet to keep my bytecoins & bitcoins. Bought both them just 20 days ago. I was little hesitant to transfer them in software wallet installed in my system. I actually have to change(upgrade) my motherboard to add another graphics card in my pc. I have OEM copy of windows 10. Since, windows considers motherboard change as a major change, i may have to install a fresh copy of windows by formatting the system. This had me worried since formatting erases all the system data. This is why i was considering paper wallets.
