Incorrect $ => BTC conversion #1953

I tried to send $199, and Zap estimated this value in satoshis (incorrectly) at 4,835,739.


Today's market price at Bitcoin/USD has not been anywhere near what this bad conversion implies.

Expected Behavior

The amount in satoshis should have been correct.

Actual Behavior

It wasn't. :D

Possible Fix

Review the code doing a real-time look-up of BTC/USD prices.


Sending a correct payment by entering a USD value and not manually double-checking that the BTC value was an equivalent.

Your Environment

  • Zap version: 0.4.0-beta
