The main aim of Betacoin is staying transparent. No one wants it to be associated with drugs or illegal activities. betacoin.info was recently launched. It's a block explorer that allows you to attach comments to your transactions. That would allow a proof of payment or a way to setup invoicing. We all know that decentralized crypto currently has a place in the mainstream and I think Betacoin will be the coin to bridge that gap.
It's been about 4 months since Betacoin launched. There has been a tremendous amount of work done in that short amount of time. Both developers and users (like me) putting together some really next level ideas. It's shaping up to be nothing short of the next Bitcoin...without the unnecessary negative publicity. Check it out.
