SXDT is completely dividend token where most of the exchanges will not list the coin due to every week they need to distribute the dividends in terms of ETH. So you need to keep track the value from Fork delta where SXDT is traded with the healthy volume.
How much dividends are you getting from your SXDT tokens ? For example how many ETH from 1000 SXDT tokens? Is this worth to buy tokens for getting dividends?
I hold 1600 SXDT.
Here are my stats in the last few weeks:
19-May-2019 reward per token: 0.000000268599803219049 ETH or my earnings: 0.000450979069604783
12-May-2019 reward per token: 0.000000341724202385230 ETH or my earnings: 0.000573754935804801
05-May-2019 reward per token: 0.000000437141640658204 ETH my earnings: 0.000733960814665125
etc ...
I hope I help you with your decision.
oh... just 7 cent per week while you are holding 1600 tokens (for ~600 usd by current price)? This is very small reward... As I remember they promised much more...
