the key is to keep buying as the price gets lower, that way you bring your average purchase lower and lower.. So if you but a lot at 10 per then buy some at 7 per, then buy some at 4 per your average would be around the 6 range. Depending on how much you purchased and that will negate most of the losses when it rebounds.. Again, I purchased as much as i could when it hit almost 4 bucks per and now its above 6...I just wish I would have had more to invest.. but at least i made out ok. When it get that low,(In fact, I had never seen it that low before) you just know it will rebound, it has too, lol... I think that it will still yo yo around but It will still slowly go upwards in the long run...
