I wonder here what Bitcoin wallet Rhonda's have used, do you think it's a hardware wallet? In 2013 maybe there's no hardware wallet and most of those wallets are custodial or a web wallet which is some of them has been lost their Bitcoin too because of their matters.
It's a good thing Rhonda was able to manage her wallet and solve the puzzle of his Bitcoin wallet and she risk his assets on random people on the internet that could be losing all of her money. Another reason whether the story is true or not true is that this was a marketing strategy so that traders will encourage newbies about their company.
