Don't forget to give some away..even if it's just a couple here and a couple there...the more people that download the wallet and it gets distributed to, the better it's chance of increasing in value. Also Mintpal voting at the moment would be a great help. https://www.mintpal.com/voting
For what it's worth I was a late-comer too and received the smaller giveaway, however, I still gave half of it away to members of a diff alt-coin community in order to spread the word. Every now and then someone tips me a couple of PMC on this thread too - no idea why, but I'm not complaining!
Personally I think the majority of the *current* big holders have probably bought in, not long ago you could buy for 0.00035 on Poloniex and every now and then someone sells a lot and you can still pick up some for lower than the current rate - always worth having a low buy order sitting there, just in case.
Although..............it does feel like things are about to change, if only because the amount of BTC orders have quadrupled recently but the sell orders have remained pretty constant.
Looking forward to seeing what the next few weeks bring.
