I tried to fund my mtgox account to buy some while they are low and it is still stuck in no-where land. Its quite disappointing watching the market rise when I know i could have had a stake in it.
BitInstant is, well, instant. I've used it before, and it couldn't have been more instant.
Also, I dumped $200 into Bitcoins at $83.5. I've been buying low and selling high as the price has been decreasing, and made over a full Bitcoin in profit. I'm ready for it to bounce, but I think it'll hang around $50 to $70 for another 5 to 7 days while the last of the sellers sell and and everyone else starts buying. This is solely a guess though; I know almost nothing about economics.
