As of Nov. 12th, 2019, Abra users in the US can now directly deposit cryptocurrency other than BTC, LTC, BCH and ETH. For a complete list regarding what we've added and what you can now deposit here's the list.
This new feature will be available for international users as well but not until December 2019. Until then international users will be unable to directly deposit a cryptocurrency other than bitcoin, litecoin, bitcoin cash, or ether.
If you'd like to deposit Bitcoin, here's how.
Some customers sell their other cryptocurrencies for bitcoin, litecoin, bitcoin cash, ether 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, ether into Abra.
