“For example, every person that has a wallet, a wallet with bitcoins, now is responsible for his own security unlike today, where the bank is responsible for the money that you have in your wallet.
“The problem is that because there are no third parties, once I’ve sent money to you, no one can take it back, so there is almost no law enforcement and no one to catch you in between and tell you ‘look, you’ve got the money, it’s not yours, now bring it back to me’.”
