BitcoinIRA, a company that allows users to create retirement funds based on cryptocurrencies, is adding new options to its portfolio.

Starting with Ripple’s XRP token from today, the firm also plans to add further cryptocurrencies in coming weeks, including litecoin, ethereum classic and bitcoin cash.

BitcoinIRA already supports retirement accounts in both bitcoin and ethereum.

The company, which is fully Internal Revenue Service (IRS) compliant, supervises the transfer of fiat retirements funds into cryptocurrency and provides “cold” offline storage for the investments.

In a statement, BitcoinIRA spoke positively about XRP, calling it “the best digital asset for payments” and stating that it is “one of the largest digital assets by market capitalization.”

Chris Kline, COO of BitcoinIRA said that customer demand for the currency has been “immense.”
