The thing about speculating in bitcoin now is that I dont know who the next round of speculators will be to pump the thing up. Where will they come from? Sure it could go to 400 from our bitcoiner group, but there's no willy bot and the Chinese seem to be done with it
there is still lots of room for growth, for example from the gold investors
daily 7 tones of gold mined = 225 055.2262 troy ounces
$1200 toz x 225 055.2262 = 270 066 271.44 daily investment in gold
3600 bitcoins mined a day x $242 = 871 200 daily investment in bitcoin
10% of golds money would be a good start
