A day after it was reported that Wall Street investment giant Goldman Sachs is weighing whether to launch a bitcoin trading operation, its influential CEO took to Twitter to voice an open – yet decidedly neutral – position on the cryptocurrency.

"Still thinking about bitcoin," CEO Lloyd Blankfein wrote on the social media platform, going on to say that he wasn't giving his approval or disapproval.

Still thinking about #Bitcoin. No conclusion - not endorsing/rejecting. Know that folks also were skeptical when paper money displaced gold.

Citing sources with knowledge of the effort, the Wall Street Journal reported yesterday that Goldman is in the early stages of creating a trading operation specifically geared toward cryptocurrencies. At the same time, it's not clear at this time if the investment bank will go ahead with the plan. Blankfein made no mention of that report in his tweet.

His comments stand in contrast with those from fellow Wall Street banking CEO Jamin Dimon of JPMorgan Chase, who has made headlines in recent weeks for his declaration that, in his view, bitcoin is a fraud.

Other big-bank executives like Morgan Stanley's James Gorman have taken a more measured approach, with Gorman stating late last month that he thinks bitcoin is "more than a fad."
