Please, tell me an example where someone lost bitcoins from a properly secured wallet...
First you give me an example of hackers stealing credit card information from a properly secured server.
Seriously do you think Bitcoin is less secure than fiat?
Yes I do. How do you propose to measure that?
I propose you to encrypt the fiat from your wallet: try to give a password to your $100 fiat paper, then you can try to do a brain wallet from them...
Stupid for stupid: I propose that you write a malware that can steal a 10$ bill from my pocket.
(And note the word MEASURE.)
Just for curiosity, if some day you use bitcoin to buy a car, how will you make sure that the address that you are sending the bitcoins to is indeed the car dealer's? What will you do if the car dealer tells you that they did not receive any bitcoins, and that their payment address is not the one you used?
Do you know you can try that 'suspicious' address from your car dealer, by sending first a few shatoshis right? Just saying...
Sure. You scan the QR code on the screen or catalog and send 1 satoshi there.
Then you check the blockchain and see that the satoshi was indeed sent to the address displayed on the screen.
You call the dealer, and Bill from Sales confirms that the satoshi was indeed deposited in their payment address.
You then send the other 999.99999999 BTC to the same address. So you think.
You check the blockchain and find that the second transaction went to a DIFFERENT address!
You call the store, and Bill says that the second address is not theirs.
Then what?
OR, TO KEEP THINGS SMPLE:
One day you find that all your bitcoins were stolen from all your paper wallets.
Then what?
(How could that happen? Hint: how did you create the paper wallets?)
