I'm not heavy into ZING so I'm not sure. Hopefully the game does well and you make out like a bandit! I think taking out the thousand to catch cheap Hive is smart, hopefully it won't go below sixteen but some are talking about a dime. Let's hope not!
Treasure hunting is a lot of luck, some skill but mostly pure, blind luck. There are buried caches of coins just about everywhere in the world, even here in the US. You just need a detector, some research if that applies to something you want to look for. and then a lot luck and sweat!
