I'm GP isn't a pump and dump like other shitty coins I've observed and analyzed!
Absolutely, told to the few crypto people I know why I bought it:
PRE-ANN: everyone had time to get ready
No Pre-MineLinear block rewards for one whole week: no halving or complicated schemes to reward those early miners and their buddies with big blocks etc - no body was late to the party all through POW
Transparent Dev from the beginning, no surprises
Everything has gone smoothly appart from some people who can't get their conf file right.
Dev knows his way in his industry and has prior experience. Has been active, delivering and building the infrastructure out of his own pocket and with the very few donations he has received. (sending some more in a minute cause as I'm guilty of this as well and it will only help my investment on the coin grow)
No dumps by the looks of it apart from miners who have to pay for electricity and ROI
Market responded to all these factors early from the first days on c-cex til now - without an army of hypers and mooners and posting memes and the usual stuff you find on PnD anns.
