There's no denying that 50 BTC is still a lot in first world countries. If that 50 BTC is converted to my local currency or fiat currency then it would be a huge amount of money and there's no need to work anymore because it will last for a long time when I am by myself and did not support anyone. For first world countries vs third world countries in fiat currency, third world countries is much more when it is in fiat and the daily necessities isn't expensive (it is much cheaper than FW country).
