Nope. I've seen large differences reported in the total value of frozen assets - $24 billion to $100 billion. Regardless, it's separate from the $300 billion investment fund. To be honest, I thought that money would be coming out of
your pockets. Apparently that's not correct, as it's supposed to be private funds from various countries.
But, any of that money (frozen assets/investment fund) going to Iran is contingent on successful negotiations resulting in a deal over the next couple of months.
