Tokens need to be staked and there is a very short window for unstaking I believe of 24 hours. Right now 487 million out of 500 Million tokens are staked and not that many are up for sale. Dividends are being released each Monday and they need to be claimed with a transaction.

One of the downsides is that it runs on EOS and you need an account which can be quite the hassle. EOS is also not the most popular widespread blockchain at this point despite the fact that it works really well.

You can see how the Dividends are adding up during the week so it's possible to estimate how good or how bad the dividends will be. Right now after 2 out of 7 days, they look to have a good week just looking at the EOS payouts.

0.0424 EOS after 2 days when the same pace continues would mean somewhere around 0.14 EOS by next monday. What I really like is that players use the platform because they want to bet which is a sustainable model and not because they want to mine and get dividends. This makes it so that the only dilution comes from the team releasing more coins which at this point looks quite a while away and they also use funds they get from that to get more adoption.

I would say, try it out with a little and make up your own mind about it. Good Luck!
