We are now at 17% of the late May price. Less than a fifth of the value at that time.
You can't blame this on "market manipulation", whales dumping or any other nonsense. Prices decline because there is more supply than demand - end of story. A large seller "checking out" only affects the price if there's insufficient demand.
In April price was 0.0011. How did DRK go to 0.028? Someone threw in MILLIONS of USD / thousands of BTC. The demand on his part was enormous. If he checks out, yes, there will be a gap in demand as he acquired a very large number of coins.
