I can understand part of the increase is related to the Peerplays sharedrop, but all in all at the current market cap of Peerplays the 5% sharedrop is worth less than 1M$ (approximately 850k$ at this time).
So IMO there's definitely something more here than just the Peerplays sharedrop. But crypto markets usually like a good pump so I guess there's some of this also.
Since the PeerPlays and BTS market cap are about the same right now 5% of PeerPlays onto Bitshares is a 5% gain for any bitshares holder. Tell me you're not excited about a guaranteed 5% return and I'll call you a bloody fibber.
and that's not even including the fact that the major exchanges are exempt from the drop, which means more like a 6-8% return for all BTS holders. Pretty nice you might say.
