I don't know what happened to @nutildah or why he hasn't been online for months but, if you can still talk to him, you can ask for his feedback from living here in the Philippines. I know he spent time in the Southern part of the country which should generally have a lower cost of living than us in the North.
There was an episode between nutildah and a staff member that - supposedly - made him cease[1] his activity on the forum. You can read more about it here[2].
So I'd love to know how far campaign earnings ($1500 per week for 5 people in my example) could be stretched. Are there actually places out there where one could not only survive but thrive by earning bitcoin on the forum?
One could argue what is a "lavish lifestyle" since it totally depends on the people and their interpretation of it. Still, I got no doubts that in some parts of the world it's totally doable living with $1500 - +- 1.362 € - per week, even if we were talking about a group of 5 people and considering that they share the same space, which directly means that they will share at least their property expenses (electricity, ISP, water, heating ...) and food at least.
Let's take for example the cost of living in Portugal[3] which numbeo states that a single person average monthly spending is 531 € (no rent included). I believe that this number is a bit higher, especially on city centers, but considering that you're sharing most of your fixed costs I'll go along with it. That's 2,655 € per month and if we add rent - a house for 5 people in a decent neighbourd in Porto hovers around 2.000 € - so that would make the total monthly cost being
4,655 €. This means that from the total of $6500 USD monthly - +- 5,904 € - you would only be left with
1.249 € ($1376) - about
249,8 € (+- $274) for each person - to spend on frivolous things/events which, at the end of the day, isn't something that would provide to be very sustainable, at least from my point of view.
One could argue that the group could simply buy a house in order to remove that 2.000 € rent - by contacting a loan which would make them pay a lower value to their bank debt - but I assumed that they've just gathered and don't have the needed funding for that endeavor...
