I think it's better to just hold. You see, I do have 40BTC and started hypothesizing on the BTC prices, and started to do some daytrading. I only ended up loosing 8~10 BTC in the process. You see, you CANNOT predict BTC prices. At a moment, you think it will go down, you sell, and it continue to raise. You then don't want to lose your investment, you buy back, and it goes down. Repeat cycle a few times and you lose a portion of your investment each time. It's totally chaotic.
You see, today Gox went up and came back down. I missed an opportunity. But now it's going up again, and I sold at 46.75. It's now slowly rising since and touching the 48 mark. What do I do? Wait (it will surely go back down)? What if that's a new low point, and goes for the sky? Do I buy at loss? I only hope to recover those lost BTC somehow, so I continue doing it, but you see, the only thing I ended up getting is more gray hairs... And less BTC in my pocket. To me it can be as worse as gambling for other persons. It IS gambling...
There seems to be some consensus that this coming monday, 3/11/13, is a turning point. With new money coming in, we will either get a massive run up, or a decline from people holding trying to sell to the new buyers. Right now we are in limbo; no one has any way of knowing what will happen before then.
Will speculators continue to buy until Sunday night, in order to have more BTC on hand to sell to the new buyers on Monday? Or will some piece of news or a rumor or a general emotion take hold over enough holders and they'll sell before the price falls Monday?
Will enough new money and demand show up on Monday to override any sell off that may occur? At what point does the tide turn?
Many questions, few answers. As time goes on, the answers will either reveal themselves or at least become less vague. This is my rationale behind waiting until at least Sunday night before buying in. Buying now, to me, is more emotional than based in reason. Emotional in that there is simply hope that enough new buy orders will show up monday to keep the price where it is or drive it up. Waiting for this to confirm itself, or at least become more likely, seems more reasoned to me.
And if it does go up a few dollars and the gains either hold or continue Monday? I've only lost out on a few dollars per coin, which won't amount to much if the price continues up.
