There is absolutely nothing wrong with holding long, especially if you got in at a good price. Key is to do your own due diligence on anything you buy, don't pay to much attention to the people on HC in terms of investment strategy, including myself, as each person has their own trading style or motivations for posting and what they do may be good for them but not for you.
For example I short QBL/MXC/BOT/ZLD a fair bit and put the profits into Ac8/MMJ/CPH/MDC, mainly because I believe these companies have larger potential and also because the retrace margins after announcement hype dies down is usually the point at which you can buy in the first place.
