This, is just part of the game. When there is money to be made there is going to be manipulation. I'd be shocked if the big financial institutions don't already have computers with highly complex algorithms trading these currencies. If any of you believe in these currencies then just stick it out through the volatility, you could even try not to watch it. Set yourself an out, figure out a spot that if it closes through that point you are no longer willing to hold and stick to it!!!! I cannot emphasize that point enough. I've seen more people hold falling stocks for no other good reason then they didn't want to take the loss, do not do that.
I'll also make the point, if you're really going to spend the time to watch it day in and day out. Really watch it, look at the volume, that is really important to what is going on. Again, if you really want to get a better feel for why the currencies are doing what they are doing. Learn some technical analysis, it will give you a much better understanding of why.
