I am certain that it will go back down again after this rally, but even so you are missing out on 30% profit by continuing to wait till it goes back down to the $200-$300 range? It might go back down to that price range, but I assure you it will not stay at that price point for longer than a day.
I don't like to play these unstable rises that are made up of stupidity and hype. To me, it's the same as passing the roulette table and cursing at yourself "If I should have called red at the moment, then I could have won big". Sure it would have been great to win money, but I'm not planning to earn with playing like this.
except a large percentage is not stupidity and hype, but real world market influencing events and conditions.
