^Yeah I agree ddf falls under the security category that is why it is only listed on a very select few exchanges.
Ddf is fund based project and not a technology based project so the token itself has no utility but represents your stake in the funds holdings. Fund has domains that it owns and earn revenue through parking and ads etc and also crypto. So yeah I agree the ddf token itself is of no use which is similar to Taas.
The dividends are generated via investing in other dividend paying projects like coss and hydrominer, selling of domain names, crypto trading and holding and Ico investing. So all ddf team is doing is investing investors money into different other projects and generate income similar to what managed funds do in traditional stock markets.
