Coinbase, the operator of one of the largest cryptocurrency exchanges, is considering adding more digital currencies to its platform.

Last Friday, the company said it is considering adding the following digital currencies:

  • Cardano (ADA)
  • Basic Attention Token (BAT)
  • Stellar Lumens (XLM)
  • Zcash (ZEC)
  • 0x (ZRX)

“Unlike the ongoing process of adding Ethereum Classic, which is technically very similar to Ethereum, these assets will require additional exploratory work and we cannot guarantee they will be listed for trading,” according to a Coinbase statement.

More Coinbase Activity

Earlier this year, Coinbase launched the Coinbase Index Fund. The fund is available only to accredited investors defined as those with an annual income of $200,000 or a net worth of $1 million or more. The minimum investment is $10,000 and the fund has an annual management fee of 2%, according to Coinbase.

After bitcoin, the largest cryptocurrencies are Ethereum, Ripple, Bitcoin Cash and Litecoin. Bitcoin futures debuted on the Cboe in December, followed by a launch on the CME. Nasdaq Inc. is still considering entering the bitcoin futures competition. Last month, Coinbased added etheruem classic to its platform.

“Furthermore, our listing process may result in some of these assets being listed solely for customers to buy and sell, without the ability to send or receive using a local wallet,” said Coinbase regarding the possible addition of new coins to its platform. “We may also only enable certain ways to interact with these assets through our site, such as supporting only deposits and withdrawals from transparent Zcash addresses. Finally, some of these assets may be offered in other jurisdictions prior to being listed in the US.”

Bitcoin, bitcoin cash, ethereum and litecoin are the digital currencies currently supported on Coinbase.
