maybe punt can add a few free spins every week for active members with certain conditions or you can also hold a monthly event to guess the price of bitcoin with a certain prize like bitcasino has done.
It is good suggestion and it can be an alternative to be implemented since I have never seen a casino offer weekly free spins for active players.
Free spins every week with low wagering requirement will be great if punt do not want to give the same as other casinos (cash rewards).
Guess the price of bitcoin also good but if it would be better if only real players who meet certain condition who can participate especially if the prize is decent enough.
