just joined and immediately tried the FAUCET, I was very surprised that there could choose FEDERAL RESERVE DOLLAR or BITCOIN. The green colour makes me very comfortable exploring the platform.. very good work

I haven't created the account at mintdice yet but what is so special about this faucet ? and what do you mean by "FEDERAL RESERVE DOLLAR"

Anyways the fist look and the site color combination is awesome.
btw, if i have much FRD token, what i can do with that token? can convert it to btc? or its only game money that haven't value?
You can find all the information regarding the faucet and our FRD
here.
But to answer briefly, the "Federal Reserve Dollar" is MintDice's play money. With our FRD you can enjoy our games stress-free and risk-free

I don't think I've found the answer to this question to the FAQ and I was about to ask this as well!
What's the difference between choosing FRD or BTC from the faucet and then playing? If I choose FRD, can I exchange it for BTC? I didn't find any such option in the menus of my profile.
