Hello everybody!
   As the title says, I have a question about paper wallets.
   So I`m thinking about creating a paper wallet and store my BTC and I know that the private key used to withdraw the funds should only be used ONCE, I didn`t find any answer about depositing funds whenever i like, multiple times. Is it safe to deposit money into the same paper wallet multiple times? Does something else occur other than simply increasing the final balance?
   I`m sorry if this question has been asked and answered before but I cannot find that topic anywere.
