Can it happen to me? If a TX doesn't confirm in hours and you don't cancel it, will it just continue to eat up eth as the days go by? Very scary...
this user might get mixed up with gas limit and gas price. Looking at transaction detail, he used 25000 gwei as gas price and 25000 gas limit. this why he ended up with actual cost 0,65 ETH. For reference to gas price, I usually use ethgasstation.
