Min bet is 100 sats. You gets some free sats in the app. I’ve honestly never deposited only used sats earned in app. Have withdrawn before tho. They have a dumb setup where there is a “rewards wallet” and a “BTC wallet”. Not sure if you can deposit directly into the rewards / betting one.

Best way to get a starting amount of a few hundred - 1000ish sats might be to buy these “token pack” for like $2 via App Store payment which should reward you with a few sats.

Don’t recommend depositing anything into the app otherwise. Can do the daily mining to build up some free sats to wager and grow a little pile
