Seems pretty stupid idea to me. I never read about CLAM before but this type of distribution is ridiculous. I have hundreds of used BTC private keys so can I get some CLAM for this? And they give me free money? That sounds dumb. Who buy CLAM then?
It is free money. You should dig your coins and sell them for "free" Bitcoins (or whatever). The best place to sell is
Poloniex at the moment.
You can also stake your coins... which basically means you let the coins sit in your online wallet and it "mines" more coins.
I think the most recent numbers are every 900 Clamcoins will earn 1 Clamcoin per day.
You should claim your money before the developers remove the digging in order to protect their and early diggers coins "value"... this was a big talk not very long ago... they want to completely change the core distribution of the coin because there was to many sellers. That is why I closed down all my Clamcoin services. It is similar to if people mined a bunch of Bitcoins in 2009-2013 and then wanted to remove Bitcoin mining because the China miners were selling what they mined.
The guy is most certainly trying to dig for Clam coins. Since it can only be obtained from a BTC address in a given date, the guy is probably doing a tresure hunt.
