would it help if bought another million to speed things up or is it just the age thing if its a weight thing then the first reward i got was just luck??
It certainly helps to have more coins. It is a combination of the number of coins and their weight that gives your chance of getting a reward. Once you get a reward the coin weight for the block of coins that produced the reward resets to zero for eight days and then starts growing again until it gets to be 30 days old where it reaches its maximum.
