edit: how do you want to have merchant adoption with a volume of 2 BTC/day?
Darkcoin also had about 15-20BTC volume before going crazy. Price rising causes explosion in trade volume.
When price stays relatively calm and non-volatile, trade volume is very low, for every coin, also Bitcoin and Litecoin.
I bet if price goes to 1000 sat from 400 sat, you will have volume more than 100BTC.
That's how it is.
Merchant adoption is a logical next step, but not a imminent one. It will come later.
At the moment a multipool, transaction anonimizer and website/forum/marketing tools improvement are much more important.
Just my 2 satoshis.
15-20 and 2 are very different numbers. Dark coin had DarkSend, masternodes, masternode payouts in pipeline. This coin has...? multipool, and "devs working their ass off" as well as "big project". Do you see the difference?
