Unfortunately not all retailers include location data – and those which do are missing some stores – so the app can't always automatically pop up the right loyalty card when you need it.

You can't try to cheat without being punished, because you're spending energy.Therefore, a miner who once owned 1% of the hash rate, can't make sure he'll maintain his percentage forever.
