I also get the server errors before it properly shows on Wink. The way it works is that 50% of the dividend pool is paid out daily. The amount depends on how much the gamblers win or lose in the specific currencies. if it's negative (gamblers won) there is no payout until the overall number is back positive.

For BFG, the current APY returns it gives are unsustainable, and either the price of BFG will need to go up or the Dividends need to come down. Right now it feels like inflation mostly influences the price while the lower dividends give a similar APY. I personally never gamble on the site (except for sports bets I believe have a positive expectation) It will always cost more in expected losses to mine BFG compared to buying it. I'm quite find having it just as a long-term hold with no expectation for the price to skyrocket but for it to give a good return vs dollar value invested.

Feel free to ask any question you have, I'll do the best I can to give an answer to them.
