I never knew that Clam could be mined or digged through old Bitcoin addresses. To be honest, I was not even aware that there are people who are willing to buy these old addresses for the sake of it. I'm not even pretty sure before what was the purpose of buying. I thought that they prefer the old ones as personal wallet since they are the most secured ones. Anyways, is it really worth buying it? How much is the cost of these old addresses and the profits it could bring by digging clams? I might start buying if it is really profitable to do so.
