One relatively unknown feature of the iPhone's Stocks app is the support of ETHUSD, BTCUSD and LTCUSD pairs.
1. The data is delayed or it is pulling from one exchange.
2. The graph on stocks isn't too great.
3. Not all the coins are covered.
4. The news, it turns out, doesn't work too well for crypto. There is a huge community factor:
- There are publications.
- There are developers
- There are government developments.
So to capture all that, you need a richer set of sources to filter through.
