If it's that cheap, one might even consider spending a few months on holiday in Nepal to save some money you would otherwise spend in large metropolitan areas.
Well, according to Numbeo[1], the average monthly net salary in Nepal is 185.45 € which is quite low comparing to what some campaigns pay weekly (it depends on your activity) - assuming that one attains maximum pay in each week for the Chipmixer campaign we are once again talking about $1,500 (1 430 €) per month. Considering that a rent for 1 person is around 113 € in the City center, you're left with a lot of liquidity ( ~ 1 320 €) to spend on whatever you enjoy the most and that gives you the most satisfaction (let it be food, adventures, traveling, etc).
Regarding the hotel prices @pmalek I doubt that for $5 is actually a feasible option (would you mind sharing the video? What city was he/she based in?). A quick Booking.com search provided me some really cheap options starting at around 8€ but from the looks of the pictures, we are talking about very basic and very poor conditions (multiple people in the same room) and most prices doesn't even include food in them. Better options start to appear in the ~250-300 € range (per night) but still no food included...
