He can keep his dollars safe in crypto. There are many ways to keep Hughes dollar safe in crypto like he can buy a hardware wallet to keep his dollars safe in stable coins or since bitcoin is now much deeper than ATH he can buy more than 2 bitcoins with his money now and if bitcoin price goes back to previous ATH price If equal then he will get 3x return of his money Which is a potential investment
The problem is to move those huge amounts of money on a 3rd world country, I don't think its easy to buy 2 bitcoins, for sure that would wake up the Bank and the Police Alarms.
And with that money for sure he can do big things in that country, even buy a new house or have a nice back up to support his family for the next years. I feel like investing all in Bitcoin is the last option of what to do with that money in that country.
