If you're 40 years old you may have 15,000 days left. If you're in hiding you're probably not looking to buy property or anything registering your assets. I can't imagine it'd be that difficult to cash out a few hundred a day in some place like Argentina which has lots of non-KYC ATMs and folks exchanging crypto. A few hundred a day is plenty enough to live the rest of your life in luxury, if crypto in whatever stable coin you're able to hold doesn't completely crash.

Remember 10 million is a lot of money, but that's really only like 700 dollars a day for 40 years. Basically enough for a luxury hotel, great meals, and a nice hooker at the end of the night every single day.

I am currently in Colombia, and there are many merchants accepting cryptos, including Bitcoin and Bitcoin cash. I guess it is because their currency has lost 50% in value since the beginning of COVID.

On localbitcoins.com you can easily find some one who will buy Bitcoin for cash. I've done this myself and the fee is not very high.

You can also use a Bitcoin ATM but fees are a bit heigh on them and they take your picture just like regular ATMs, so it might be a little bit dangerous.

So to conclude it really depends where you are. I think that for example Medellin is a perfect hide out. And most things here are 4 times cheaper here than in Europe or the U.S.

No one is going to give you advice on how to break the law, but a google search doesn't come up dry on nations full of illegal immigrants that tend to be overlooked unless they commit some grave crime or have a very serious political enemy. It's also worth knowing that strict immigration law and power of the government to enforce it don't really go hand in hand in many shitty 3rd world countries, and in some countries the law really only extends to bigger cities where federal police have power.

I'm sure he can find somewhere with less scrupulous officials that he could bribe for some official documentation.
