The only way I can think of it making sense is if @syklep is from a country with a currency that has inflated 10% every year with respect to the dollar for the past 60 years, and that they assumed you'd buy local currency with the $30m when you get it and now would try to sell it back for dollars.
I don't think that currency exists though. The closest current example I can think of is if you're Argentinian and you bought $30m worth of Argentinian pesos in 1992 which would be worth ~$35k today. But that is due to relatively recent hyperinflation, not yearly 10% inflation, 10 years ago it would still be worth $4.3m, 15 years ago $8.8m.
You'd have to be seriously asleep at the wheel (or being strong-armed by local law enforcement, unfortunately) to keep your liquid currency parked in a hyperinflationary currency.
