Yep, I'm holding on tight to my shares. I made the mistake of selling my 8.5 million shares back when we were stuck at .0008 (I was trying to make money to buy more PINR shares, though). I thought that Twitter would provide an indication of when the price might jump, but the share price doubled out of NOWHERE, and I missed out on it. I'd probably have around $16,000 in my portfolio if I hadn't sold any of my PINR shares.
Oh well, I got about 734,000 shares right now and I'm not letting go.
