In my humile opinion the multipool should pay miners more often ( I have no problem getting paid once per day but other do have).

And if the multipool buy coins 2-3 times per hour at least  , there will always a flux on the market and other exchanges might want to add SUM to their markets.

If the multipool needs any help I am happy to help a little.



edit:

As you can notice , I've addedd that 2 Th/s for 3 days , let's see how it goes.
