Do we earn more rubies if we have more rubies on our wallet when mining?
100 rubies in wallet -> mined 5
1000 rubies in wallet -> mined 50
10000 rubies in wallet -> mined 500
Is it like this?
Correct the more you have the more you will earn, think of the quantity of coins like adding mining rigs to your wallet; more coins = more hashpower. Just be sure to password protect your wallets and remember you need to unlock them to allow staking after 12 hours they will mature.
Just to add on, it ends up equaling about 0.000136986 Rubies/day per Ruby held.
Good this helps with figuring how many coins I need.
