Philippines.

Get a beach house, or live in the city, or get a few acres of land ... Put a wall around it. Hire security or bodyguards.
When you have kids, hire a nanny for each. Send them to private schools.
Cash out in 2 or 3 major exchanges, or make it a daily routine to sell to locals.

But, don't do drugs.

A relatively large 3 to 5 bedroom, 2 or 3 car garage home, with a swimming pool, in a gated community will set you back about 10 to 20 million pesos, or 200k USD to 400k USD.

*edit* at 53, expect to live to maybe 83 ? so that's 30 years. You better have at least 1000 BTC (at today's prices) if you want to be comfortable without too much additional work. Get a token job for income tax purposes, but usually the government will leave you alone if you blend in.

That's 3 BTC per month for 30 years, more or less. Don't exceed that budget. You wouldn't unless you do something stupid. Just be smart about it. As a foreigner, you might spend more on local food (coconuts?) but just tip the waiters an extra 10~15% and you will get excellent service most of the time.

All gas stations are full-service, by the way. You can't gas the car yourself, they won't let you. Hire a chauffeur / driver for $300 USD per month. Double that amount if he acts as armed bodyguard.
