A lot of the world lives in places where wages are low compared to us corpulent white devils and opportunities are limited. What might be pocket money to us could be enough to run an entire life on a pretty comfortable basis elsewhere, however things come and go so rapidly on here I'd remain exceedingly conscious of that if I was fully dependent on earnings from it.
If I was a brand new account with a need to earn I'd have no idea where to start unless I had some already existing skills I could market, even then I'd be able to make much more from them elsewhere. There's the Bitcoin tax where it's acceptable to pay you 2-50x less for the honour of receiving payment in BTC.
