Can someone please give me a rough idea how many people are holding blackcoin and / or how many wallets there are. I'm working on something and need this info. Thanks.
Try this link:
http://agran.net/bc_getbalance.php?top=100 and if you change the 100 to a 10000, you should get all wallets with something in them. If you want to know how many wallets there are, including zero-balance ones, make the 10000 a gazillion.
