Two important things - Is there a correlation between the price of BTC and the downloads of coinbase? Is it because the higher the price of BTC there is more interest to download and use coinbase or the other way around, as more people are interest the price goes up and when it declines so does the price?
- Is downloads the key metric to look at? At some point coinbase will reach full penetration (not even close now) and even now most people that are slightly interested should have already downloaded, more important to measure interest could be active users
