he market has already anticipated/realized the impact for the split. That's the reason for the dumping within last three weeks.
I very much doubt it's this. Alphabay has also gone down - considering they took in almost $500,000 of transactions per day, they were a big part. This always happens with a market take down and I think most people are preparing, if anything for a short crash and then back to normal. You think people won't lap up cheap coins and push the price back up if it drops below a certain %?
For every seller, there's usually a buyer who will buy cheap coins off you ^_^
