traders are dumping and buying 100k per day? can you point me the source of this? i don't really care about the demand and supply but only the supply so i can compare better the reduction in the "mining supply"
if it's indeeded 100k per day than ok 1800 is nothing to that lower than 2% and will cause a 4% up in demand like you said
If you go to
http://bitcoincharts.com/markets/, you can see daily exchange volumes for most exchanges. The total today is about 100k BTC, but it doesn't include all exchanges.
