At this time, it's not possible to directly deposit a cryptocurrency other than bitcoin, litecoin, or bitcoin cash into Abra. However, we are working on making this a feature in the future.
If you'd like to deposit Bitcoin, here's how.
Some customers sell their other cryptocurrencies for bitcoin, litecoin, bitcoin cash so they can bring it all under one app with Abra. To do this, these customers will use an exchange or a conversion service such as ShapeShift or Changelly to get bitcoin, litecoin, bitcoin cash into Abra.
