If thats your strategy then go for it. Nobody can stop no one from selling or dumping because it happens all the time. Some will take quick profit and some want to hold out for long term profit. It will work out for both types of people depending on what they are aiming for so everyone gets what they want. Quick profit takers get fast money upfront but also help long term holders that are waiting for maximum profit. Long term holders are willing to let go of short term profit. Its all a gamble anyway and after all a market.
