Online banking spells end for dirty money stories

Downtime was happy to read the story about the binman who found £10,000 worth of ripped bank-notes in a dustbin. Best of luck to him: if he pieces it back together, the Bank of England will replace the cash with fresh notes. 
It is nice to see a good luck story at Christmas, but Downtime is concerned that cash is becoming less available with the rise of online banking and the card culture. How will anyone find their riches by accident? 
“Your honour, I mistyped my online banking account number and password and they just happened to match a millionaire’s who lives next door to me… What do you mean, 
‘rooting in his bins’? I was looking for my hedgehog.”
