Where should I look to know the btc price? I'm checking coinmarketcap and says this:
$0.828768 (-18.45%)
0.00030527 BTC (-15.47%)
0.00328414 ETH (-15.44%)
Market Cap
$74,347,396
27,386 BTC
294,615 ETH
When you talk about 27k you are talking about market cap or about the price?
I repeat I'm a noob trying to learn about all of this, sorry if I make dumb questions.

Bolded area is the BTC price. In this example, people would discuss this as 30k. It just means 30,000 satoshi.
