what has been the most common mistakes with people losing coins via paper wallets over the years?
i heard something along the lines of you can only fund the paper wallet once? or is it you can only redeem on a paper wallet once & any other coin not redeemed get lost forever?
you can only spend out of the paper wallet once.
It depends on the client you use to withdraw the BTC with. I would try to avoid those clients that don't let you choose a change address.
