(Reuters) - Robinhood Markets Inc said on Wednesday it would roll out crypto recurring investments, allowing customers to buy digital coins commission-free and with as little as $1 on a schedule of their choice. "The crypto markets can be volatile due to the nature of the industry. Investing on a recurring basis can help you focus on long-term growth, reduce risk, and reduce the stress of timing the markets," the online brokerage said in a blog post blog.robinhood.com. The new feature allows customers to buy crypto currencies on a daily, weekly, or a monthly schedule.
