The price seams to be going up currently, but still i expect to see a lot of flash crashes this year, all leading to the date of block halving, and
then the magic will happen once again, and we will see prices of over 500$ per coin for sure. All this p&d show is just to shake off weak hands.
The price rise from $380 to $450 is not a pump and the drop is not a dump. That is just reaction to the block size debate.
