With this new major exchange coming on board and stress testing instantx/instantsend is it now time to implement the 2MB blocks?
If this would finally bring us some tx volume - I guess so. So far our blocks are 1-10kb however, so we still have plenty of free space. Not sure which path bitcoin is going to take trying to solve this issue (segwit or BU or something else), so it's hard to say how to stay compatible and expand at the same time. Personally, I really like the idea of dynamic block size limit, specifically bip104
