Pitiful amount of accessible rewards=waste of time and effort
Yes, they give you SG as a “reward” for shopping at attached stores. But you can’t ever withdraw more than a couple cents worth. You can’t use your accumulated SG tokens to buy a premium membership. Rather, you are required to buy SG through Coinbase Commerce. Your withdrawal limits are determined by your previous month’s purchases in linked store apps/sites. But the threshold of purchases is so high that your “approved” SG is minuscule. Rest assured that the developers are banking all the advertising money they’re getting from their “partners.”
