Is there some free faucets too @OP?
Seems that you did not read the main post first before asking, here is the answer:
Faucet,you can claim satoshi 1-5 every 10 min and tickets.
No don't acquire a license because many request it just get it to show to the people that your business is legal, many gamblers will get turn off by this and might people will give a bad impression since you didn't have that.
I will just look at this site before things are set and it's risky to try this.
Do you think that gamblers look casinos just because of its license? I'm quite sure many crypto casinos started their business without licenses and they can survive to get many players without any issues. One example is Bitvest, this site has been operating for years without licenses and this site is one of the trusted bitcoin/crypto casino till now. Better for dualdices to focus on how they can build their reputation first instead of acquiring licenses.
