I think that altcoins are largely the reason behind this, it's taking time for money to flow out of alts that were pumped to much too high levels in the recent months. Once they've returned to more normal levels the money can then begin to flow in to the stronger alts as well as bitcoin.

Couple that with uncertainty around bitcoin price and what's a true reflection of its value, along with where support levels are and we can see why things have been struggling.

On the wall street point. It's easy to say that we'll wish we owned more if there's a large influx of funds from wall street but similarly we could say we wish we owned less if that day never comes.
