RE: The Distribution of Daily Rewards for Alpha Vials Holders Started! + I Bought 4 More Alpha Vials + Focus on ZING Market Value + New Rewards Sent to My Referrals (ENG/ITA)

Do all Claim Rewards go directly to stake?

Yes and the claim is manual and you can do it every hour. Only the rewards from the pool you receive them automatically in liquid form in your Hive Engine Wallet every 24 hours.
In my table I calculated the daily gain and that's why you only received 60 ZING because when you made the claim it had been a few hours since the snapshot ;)

Do you know if there is a minimum?

I think there is no minimum although I have not verified with very small delegations
