Are you swing trading this? As long as you're not insistent on flipping it in a matter of days and you're bullish, you made the correct call IMO. Buying in the 0.17's vs 0.16's isn't going to make much of a difference, and the insurance of having your position now to prevent the risk of jumping on a rocket later (or missing it completely) probably outweighs the risk of seeing a drop back sub-0.15 sometime soon.
