at least 10 Bitcoins per month
What.. forever.. or over some more specific timeframe? Seems like a bold pledge to make given nobody has any idea how much value 10 BTC might represent in future.
True.. 90% of the world's population can't afford spending $80 (current rate) per month to buy random services and products online. Most people live on $1-$5 per day (that is, just to survive)
Hell, even lower and middle class people in first world countries are struggling just to pay bills.
Remember that people in first world countries with internet access are a minority.
I'll be spending bitcoins as long as there is something viable to buy.
I don't see a big market so far; the only things I've bought is extenders from Cablesaurus & beef jerky from bitmunchies.
