Market cap is a term borrowed from the share market[1]. I don't think it's technically correct applied to BTC but it commonly is.
Market cap growth as a percentage just means, if all BTCs in circulation are worth $10bn today, and $15bn tomorrow, then the market cap has grown by 50%.
I didn't use the price of the coins themselves as BTC is being minted more slowly than DOGE.
