Now it is shown that only 60 mil coins are being sold what happend to the original 70 milion if there has been a modification it would be nice to know.
I saw that too, I think it states on the site and in the terms that some of the 70 million were sold in a pre-sale to early investors.
I think they were trying to rectify how many BCY are actually available for sale right now, that people can buy.
It's also stated in the OP:
I believe the total available is 70million - presale.
I'm just saying not 100% sure, but it could be an answer to that.
