Yep, they set the maximum cap to $45 M that's too much. Also now they are selling 2824 SNM per ETH compared to previous 606 SNM per ETH.
I think you have not yet seen the price of ETH highly increased nowadays it seems ETH price increased about 5 times from April 2017.
They need to adjust the SONM price in the reasonable way for all investors joining and I think it will be more successfull than before.
