I appreciate that dsamuel24 finally decided to play a little more safer route. In my opinion it would be crazy to load a mobile phone wallet with an amount of coins that easily exceeds five- or six-figured $$$ equivalents. Simply don't do this because even when it's an iPhone (how are those safer than other phones, anyway, unless you blindly believe all the marketing shit of big brands), people do all sorts of internet, app, (a)social media shit with their mobiles. And yes, there's malware in Apple Store, Google Play Store and any other less official stores, too.

I don't know why for such an amount of coins people don't use a decent hardware wallet (I'm not speaking of Ledger crap).

Paperwallets are dangerous if you don't know the basics of Bitcoin transaction mechanics, especially when you may want to spend coin(s) from a paperwallet only partially. You have to understand how to do that properly without accidently loosing the rest you don't want to spend. (Learn basics here: https://learnmeabitcoin.com) Fortunately Electrum wallet is smart enough for this if you only import one private key and spend only partially from coins controlled by this one private key.

I don't recommend to use paperwallets anymore, when much safer decent hardware wallets exist, especially for larger amounts of coins.


Your ignorance and unfamiliarity may leed to a potential loss of hundreds of thousand $$$ when you foolishly disclosed that your father holds "a couple of BTC". At minimum this might be just two BTC, maybe more. Learn, that nobody needs to know how much Bitcoin you or someone close to you have.
