How much % dividends people receive last time? And when Spectre will be listed on some good exchanges? More than half or year after ICO and still only Etherdelta? At last middle exchanges would be good. Like Kucoin etc. 
SXUT has been here for a long time: bibox.com
SXDT will only be on IDEX and other decentralized exchanges. This was announced during the ICO. The reason for this is dividends.
Yes, not only spectre there are ma y dividends token not listed in many exchanges because every quarter they need to do some changes that's why most of the exchanges will not listed in higher exchanges.
Ehm nope, they won't list SXDT because it's a security token. About percentage, they pay 2% of trading fees from their platform weekly (I still don't understand if entire DALP's income is paid weekly of not)
Weekly dividends are based on platform volumes while annual end-of-year dividends are based on the excess growth of the DALP (Decentralized Autonomous Liquidity Pool) up and above preset benchmarks at the start of the year.
So the combined dividend per token is estimated in being $0.03 ? What happens if you don't claim your dividends for a few years, waiting that they become interesting enough to justify the KYC procedure. Will you get also the past dividends?
