Price decrease will always happen especially after every airdrop. This is natural because there are a lot of bounty hunters enrolled in the signature campaign of PRiV who are just here just for the money and they definitely don't have any concern whether this coin will progress in the future or not. As long as they receive their token, they will go ahead and sell it right away, in any price at that given time. Expect this to be happening up until the last airdrop.
My view is, we will see the true value of PRiV after the airdrop has been given and the last batch of bounty hunters sold their coins.
Hard to say what everyone who sells. sells for or the reasons they hold if they are holders. Tho some could be selling at any price they can get whenever they get there air drops rather than holding them till they are worth even less when all the air drops are over. If someone does not see this coin as having any real potential of going up in price they would be foolish to wait till they were worth even less to sell. Same as it would be foolish for anyone who truly believes it will go up to go and sell low. Its all a matter of what someone sees for the future of the coin. Cause surely no one is selling their coin each week cause they are in dier need of money to maybe go buy a pack of smokes or a 6 pack of beer.
I don't care if people sell coin at 1 sat. More people will have this coin, because once some developments are out, this coin will surely make you 1000x while BTC at current price can make you 3x with huge investment.
