As a Clam holder I would appreciate ending the digging process. Especially since it has been a while. People who are interested in Alt-coins probably have heard of clams by now. The end of digging could bring more interest and money into the coin.
Is it possible to prevent further digging though? Isn't digging just using a previously unused private key to move coins. So to prevent that we would have to remove the ability to send coins which were initially distributed but have yet to be moved?
Yes, and as a bitcoin holder I would like it if they stopped block rewards. We can stop staking for clams too.
The whole point of clams is that they were fairly distributed, just because some have taken longer than others to dig theirs, it doesn't mean they shouldn't be able to.
