Like you, I would expect all this new money flowing in to increase the price, but to date, its clearly not happened.
I've a feeling a few people that can coordinate "flash crashes" have made a huge amount of money in the last few weeks, at the expense of noob account holders.
Love to think this won't continue but when there is such cash to be made, further attempts are inevitable. Will they succeed? Look at the price at the end of May and decide then. This new money should be pushing the price up to $200-$300. If it isn't, we will know the flash crashers are still making a mint. People won't keep pouring money into a market if they keep getting hit. Bad news spreads much more quickly than good news. bitcoins will get a reputation for being a scam asset. I sincerely hope this doesn't happen.
'To date its clearly not happened' ? So the climb up to 266 didn't happen? And then an incredible climb from 50 to 166 didn't happen? A climb that happened so quickly we needed a rather strong and healthy correction to the 120s to test support twice. The price has clearly been increasing. We haven't made new all time highs yet, but those don't happen every day, especially after some large corrections.
