If I had several million to invest I would definitely be more conservative, go for the sure bet, like the big guys, and like MJ (he says). After all a small percentage gain on a lot of money can still be substantial. Like most here though my investments in exploration stocks are quite small, money I could lose and still survive. Limited knowledge also means higher chances of buying and selling at the wrong times. So reading all sides and opinions here is important. If only totally positive opinions are allowed I personally would become somewhat sceptical.
