Bitcoin Investment Trust certainly does look like it's hugely overvalued

Citron's Andrew Left takes a short position

Bitcoin is trading at $18,500 but a company that simply stashes Bitcoin is trading a nearly double that.

Bitcoin Investment Trust is a company that holds Bitcoin, sort of like an ETF.

Short seller Andrew Left at Citron Research is out today saying he's betting the gap between the company's price and Bitcoin or Bitcoin futures will close. He said it's only a matter of time until it's arbitraged away.
