In my opinion with any spiv trade (and I use the word spiv with reservations here because 88E is really anything but - perhaps penny stock is more accurate) you buy the story or you don't, you assume if it doesn't work it's worth nothing and you therefore don't throw anything at you aren't completely happy to lose 100% of. Some of the shareholdings people on HC report here truly make my eyes water. If you worry you have missed the boat and you like the story just get into it at whatever level you like. I am in this for either zero or many hundreds if not thousands of eventual percentage return over any possible timeframe. It's a binary trade for me and worrying about price is largely irrelevant. Yes, of course it matters in the eventuality it's a great success and you worry about what you missed had you bought lower, but none of us have a crystal ball.

Short version, if you like it, buy it. Assume its likely to be worth zero and size your position accordingly.
