I also recently spotted that there are major updates to the underlying tech coming, and they can be ported to bitshares or any other graphene chain.
This may not have been priced into bitshares yet, so once I think Bitcoin is consolidating I'll be grabbing some :)
This is basically crypto-investing 101 haha. Buy when you hear a big upgrade coming up when volume and price have been low for a while. Excited about what happens after btc settles down or starts losing dominance over the other currencies.
