Nevertheless it doesn't add confidence as a whole.

Look at the buys vs sells on Bittrex:



The volume is just weak hands panic selling over the top of the order books at any price, which has been the story the last week.  But the other story is that experienced people are either holding or buying cheap and mining hard whatever the rewards as they expect the price to rise later.  So those are the 2 sides to this, because its typical a coin like TAC doesn't get recognised until its fully developed then people get the innovation, same as DRK.

Don't worry about the short term price, lower price is better for long term investors right now, if you don't see the fundamentals in play here then don't take the risk.
