Gambling on epicdice itself is very stupid, you have a negative expected payout ratio because of the house edge. And i once spend like a week trying to beat the casino with all the strategies but none work because there is no skill involved with this type of gambling.The only thing you can do is prolong your gambling experience with a martingale strategy but in the end you end up losing so it only makes sense if you could collect some type of tokens for playing. That's basically the only workaround you have. (In theory a martingale strategy never fails but you would need to have unlimited amounts of money.)
The problem with all that delegation shit is that they can't give more then people would otherwise earn. Let's say for example your voting power is 1 steem per day with curation rewards already taken into account. A dapp can't really payout more then your voting power is worth. Most dapps give worse returns then selling your voting power with minnowbooster or smartmarket.
Besides that many people don't understand inflation. You only earn with your delegation if the return is higher than the annual inflation otherwise it makes no sense.
But in the end it doesn't work trying to educate people and it makes no money. Just keep it quite and take the money instead. Let them gamble, i'm market making epic tokens instead :p Casino's are fun! The now closed Moonsteem casino was also like this. You could earn big returns simply by not gambling but doing the math and investing in the casino instead.
