I had a query, say if I have more than 30k stats so will I automatically get eligible to receive interest on amount daily or I would have to deposit it somewhere in order to receive the interest? Thanks in advance.
You will be eligible with an amount higher than 30k sats! You will get an email notification for that as well! Few times I withdrew all I had and later deposited again, each time I got an email that says I opened special benefits or something like that!

I have been saving them +20 days, I am not sure to spin them now or to wait a bit more... when I got here already I might wait to 200 spins, maybe one can be Rolex!

You just made me jealous.I keep spending my daily spins but from now on I will save at least one month which should be about 150 or bit more free spins for me,not counting the Email ones,those I will click daily as they expire.Hopefully I hit a big amount of Satoshis or RP as for the Rolex I think that is impossible even with 1000 spins.
