I am having problem figuring out why my application is doing endless render.

Inside, My stateful component, I am calling a redux action in componentDidMount method (calling componentWillMount also do endless render) 

```
class cryptoTicker extends PureComponent {
  componentDidMount() {
    this.props.fetchCoin()
    // This fetches some 1600 crypto coins data,Redux action link for the same in end
  }

  render() {
    return (
      <ScrollView>
        <Header />
        <View>
          <FlatList
            data={this.state.searchCoin ? this.displaySearchCrypto : this.props.cryptoLoaded}
            style={{ flex: 1 }}
            extraData={[this.displaySearchCrypto, this.props.cryptoLoaded]}
            keyExtractor={item => item.short}
            initialNumToRender={50}
            windowSize={21}
            removeClippedSubviews={true}
            renderItem={({ item, index }) => (
              <CoinCard
                key={item["short"]}
              />
            )} 
          />
        </View>
      </ScrollView>
    )
  }
}

```

In CoinCard I am literally doing nothing besides this (Notice CoinCard inside Flat list) 

```
class CoinCard extends Component {
  render () { 
    console.log("Inside rende here")
    return (
        <View> <Text> Text </Text>  </View>
    )  
  }
}

```

Now, When I console log in my coincard render, I can see infinite log of **Inside rende here** 

**[Question:]** Can anyone please help me figure out why this could be happening?

You can [click here to see my actions](https://github.com/irohitb/Crypto/blob/master/src/actions/cryptoAction.js) and [click here to see my reducer](https://github.com/irohitb/Crypto/blob/master/src/reducers/cryptoReducer.js).

**[Update:]** My [repository is here](https://github.com/irohitb/Crypto) if you want to clone and see it by yourself.

**[Update: 2]**: I have pushed the above shared code on github and it will still log endless console.log statements (if you can clone, [run and move back to this commit](https://github.com/irohitb/Crypto/commit/cf0d34cf7f533730025c49c876f436519b489ef7) ). 

**[Update:3]:** I am no longer using `<ScrollView />` in `<FlatList />` also when I mean endless render, I mean is that it is endless (& Unecessarily) passing same props to child component (`<Coincard />`), if I use PureComponent, it won't log endlessly in `render () {` but in `componentWillRecieveProps`, If I do `console.log(nextProps)`, I can see the same log passed over and over again
