Actually, the price would really be $9.26 at a 5% increase per day since the 5% should be compounded, i.e., based on the newly increased price. My GUESS is that if you took a survey less than 5% (and maybe 0%) actually think that the price will continue to go up 5%/day for the next 15 days but it doesn't have to for a double to occur because the possibility exists whereby some news can cause the price to double in one day and surpass $8.19 and $9.26 and we all know that news sometimes comes when it's not at all expected. I'm not expecting such news but eventual reality has little to do with my expectations.
Although I agree with your trading strategy (to an extent) because I study charts daily and trade around my core as often as I feel, I fall short of recommending (not saying that you did) that others do it or that they're deficient because they're not doing it, especially since some people clearly don't want to trade. Let's face it, when "traders" are on the wrong side of a trade they often urge others to buy, sell or hold so as to benefit themselves. Yes, "investors" are guilty of this as well.
