The promotion is part of a multi-stage rollout of bitcoin services at the company, which has integrated its platform with bitcoin services provider Coinbase.
The company's Plus Program requires a minimum $25,000 investment, and associated fees can be paid with bitcoin. Bitcoin investments are currently not available with its $5,000 basic investment program.
Throughout the conversation, Kane stressed that, while its account may require a sizable upfront investment, its target market is average investors, those who have between $50,000–$200,000 to invest.
"The average client with us has $250,000, that's actually the average account size in America. However, if you have $200,000, you're really in the dark, most high-quality investment solutions are $250,000 and up," he said.
