What? That's not how inflation works. Even left to rot in a bank account it would still be 30 mil today. Not worth as much as 30 mil in 1990 but still worth as much as 30 mil in 2024 because it is still 30 mil.
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.
