Is there a maximum and minimum reward tier value?

There is no minimum charge but please note that there will be a fee of 3.4% + $0.50 for each transaction so if the minimum amount is below $0.50, you will receive nothing. 

We recommend at least $5 to cover all costs incurred or if you are thinking for an appreciation reward, $1 would be optimal.

There will be no maximum reward tier value.
