Now the reward for 24 hours is about 40-50 coins, which is only getting smaller every day, so the extension of the tap without changing the number of issued coins per day equal to 1 million, I do not think it is interesting(
I would suggest as either complicate the collection, that would raise the reward( for example, did not collect on time - burned) or something else like that
When the reward drops to 5-10 coins per day, no one will use the tap.
