How can I find out if someone claiming to be a Bitcoin sales manager?
By default will they be scammers. Bitcoin is a decentralized currency. It is not linked to any Government, corporation or business. Anyone who claims to be a sales manager of Bitcoin is by default lying. Bitcoin can only be gotten through an exchange or, if possible, bought from miners directly. Another option is by mining Bitcoin yourself. The final option is by selling products and services and being paid in Bitcoin. Anything else is a scam.
