3dp chart, page-262

Mate I was lucky enough to get in @ 3c and then 4c early on. I've seen it steadily climb and my latest pick up was at 21.5c 1) because I had a little bit of money to spend and 2) I was getting scared I'd miss the boat and it wasn't worth holding out for more of a dip. That's just my thoughts - I'm a novice at this so certainly don't take my rationale as anything but a novice investor basically taking a semi calculated gamble and wanting to ride the train.
Theres plenty of experiences people on this forum with really in depth research and analysis of the stock that can help inform your decision.
Personally I don't think in the long run you'll be disappointed getting in at around the 21c - 22c right now but I don't think that price will last a great length of time - IMHO.
