IMO,

The Panda Devs should invite WhalePanda over for a Private Dinner or at least a personal call and explain exactly how they are going to Grow the Value of Pandacoin. Anyone who spent Thousands of $ollars on a coin deserves at least that. And others questioning the guy after the amount he has already put out,
Whoa it says a lot about the ones asking the questions.

PandaCoin will continue to drop until 1 of the following happens,
1. Someone or a group of someones buy out all of the Dumpers.
Doubtful because of the sheer # of coins, higher you raise the price the harder it gets

2. Panda Devs come up with a way for Pandacoins to be used up or destroyed to decrease the number of coins.
Which will automatically increase the value of the remaining ones.
Make a game where 5 people play a game, each putting in 1000 pandacoins at a time.
1 player wins and gets his pandacoins back, plus a ¼ of the other players coins for a total of 2000 coin.
Then destroy the remaining coins from the other 4 players. (3000 coins destroyed)
You have a game where the winner doubles his pandacoins, and the majority of the losers coins are destroyed. Enough people play the game and your pandacoin population problem goes away.

3. It becomes a part of the global economy.
at least 3 to 5 years away

Biggest Danger to Panda
The Dumpers will Crash you with the sheer # of the Pandacoins.
Find a Way to circumvent that , and then you have time and a shot at being in the top 10 coins.

Good Luck.
