For clarity -- this is not cryptocash or cryptocurrency. Its is a User Issued Asset (aka token) on the WAVES cryptocurrency blockchain. We typically call these 'cryptoassets' or 'tokens'. You cannot mine these. They are purchased via the WAVES network, in 'BTC' (which is another 'pegged' asset on the WAVES chain).

Edit; I bought one whopper coin 3 days ago via WAVES. I paid $0.50USD (majorly overpaid for it!)
