IMO replacing the divident system only to go on bittrex is a bad close term idea. I bought SONM for long term and for its dividents, if they change their idea I can probably sell it like ICN..
In my opinion this solution is great to prevent not get listed on several exchanges and can be adopted from many other coins/tokens to get conform with their local laws of their county, of course with some modification because there will be additional benefit needed for the token which doesn't get dividends. May something similar is possible for SONM.
