but when it comes to casinos, you can only claim from the faucet if you don't have balance in your account. it is not that you can claim again even if you have the minimum balance to play.
on the other note, it is nice to hear that there are a lot of plans for mintdice. continuous improvement will aid in keeping the interest of players alive. they will look forward to additional features or rewards and what's in it for them as a gambler or investor.
Faucet has its role is a free money to test casinos and to get familiarized yourself with the casino platforms. How to gamble, win and lose money (faucet money). Some casinos ask for real deposits to withdraw money.
As I see, faucet plays its role to keep gamblers on casinos, and don't leave when their balance falls to zero after lost gambling orders.
Faucet is good for testing the gambling platform only but if you are looking forward to the money that might you get, you might be wrong.
It needs to have at least 1 transaction of deposit before you can allow withdrawing the faucet even your faucet claim reached 1BTC.(which is impossible) Afterall, the faucet is good to lure gambler and will stay on site.
If dev of this site want implement that for people to test their sit then it's good but if this option abused by some crazy bettors then it's another story then better to take this off and have another option like putting some test money for fair testing and abuse free site. But it's up to the owners decision on what is the counteraction they do since it's really good thing to have those option since actually it's certainly helpful for stretching up when betting.
