Good news has arrived for four altcoins, including XRP and Dogecoin from the US giant company (DOGE)!

The White House's increasing interest in Bitcoin and altcoins has also mobilized the American giant company.

According to the official announcement, leading brokerage giant Interactive Brokers is expanding its crypto trading services by adding support for four altcoins, including XRP and Solana (SOL).

Accordingly, Interactive Brokers has added four new altcoins to its platform: XRP, Solana (SOL), Dogecoin (DOGE), and Cardano (ADA).

The large company currently offers Bitcoin (BTC), Litecoin (LTC), Bitcoin Cash (BCH), and Ethereum (ETH) services on the platform.

Customers with accounts at Zero Hash LLC are offered services for SOL, ADA, XRP, and DOGE; while customers with accounts at Paxos Trust Company are only offered SOL services.

Steve Sanders, Vice President of Marketing and Product Development at Interactive Brokers, said, "Adding these new altcoins provides our clients with greater flexibility to diversify their portfolios and take advantage of opportunities in digital assets."

Interactive Brokers also promises low trading fees amid an increasingly competitive crypto market. Accordingly, the company offers trading fees ranging from a minimum of $1.75 per trade to between 0.12% and 0.18% of the transaction value.
