Bitcoin is permanent money. It suffers from the same provlem. Introduce it as a global currency and one day you will realize that there are more than 20 million Bitcoin. I can guarantee it. Permanent money simply doesn't work. The world isn't as permanent as gold.
You don't understand Bitcoin, then. Look into the halving mechanism. The supply isn't a variable just set by anyone. And even if you mess with that algorithm, the rest of the network would have to accept the changes (which would designate a hard fork and create a new currency that wasn't Bitcoin).
