Citigroup may have found a way for big investors to cash in on crypto-currency.

Citigroup has created a custodian-held crypto-currency product that could be purchased by traders like any other stock.

It’s called DAR: Digital Asset Receipt. Modeled after a foreign investment paradigm. This will give investors a way into cryptocurrency without worrying about the massive fluctuations.

Bitcoin surged to $20k a piece last year- and then tanked- riding a weak wave around $5-6k. But getting a foot in the door to major brokers on Wall Street could give digital currencies the foundation it needs.

Also, a Bitcoin ETF has been voted on several times by the SEC, all failed due to lack of stability. Citigroup’s new structure could breathe new life into that as well.
