I know that the amount of dividends you get is lower as there are more and more tokens getting mined everyday. That's why I try to play everyday to get some more tokens so your daily dividends stays the same. They already have a monthly burning program and every time when they do it, the dividends are higher the next couple of days.
And you see the obvious problem in this; You have to use all your dividends just to keep up not losing your dividends. It doesn't really require complicated math that at any point you are better of selling your tokens. Unless they fix that tokenomics game theory somehow and you have hit the gold mine. I personally wasn't going to wait for that and sold.
Occasionally i still play for fun in there but not because i want BFG tokens.
