The hash rate is a lame 120 MH at the moment. My theory is that if a multipool is introduced, the buy pressure increasses and prices will go up. it will quickly be evident that its more profitable to mine it directlly, and will jump to mine it till it reaches a kind of equilibrium where the prices is always optimal and slowly rising, miners switch between multipool and mining directly as per their profitability asessment. The short dip in the hash rate after the multipool's introduction will quickly be filled by miners bypassing the multipool
