The mood in Bitcoin has certainly changed the last two weeks.
With GBTC just having launched and swedish XBT launching in May, it's still unclear how these ETN's will affect price.
Btc being accessible on NASDAQ (or rather, shares of a fund owning bitcoins) should attract some interest and increase volume, but it may take some time.
Right now the key level is around $235.
Personally I think the overall momentum has shifted to Bullish and that we are about to start moving up with increased confidence, but it's just a feeling.
