I hold GKP, was one of the lucky originals that got in before the 10fold jump. Only had £500 in though as was when I first started out and took a lot of the profit last yea. Still holding a reasonable amount of shares, I dont think its done as there is lots of oil just problems with the transportation.
Im not too bothered either way as Iv made good money from it, the rest I will leave in for a while to see what happens as its pure profit.
