A month after offering OTC (Over The Counter) Bitcoin options, American multinational investment firm Goldman Sachs is now reportedly contemplating adding OTC Ethereum options to its growing list of services. Andrei Kazantsev, the banks Global Head of Crypto Trading, recently revealed the idea at a Goldman client webinar, citing rising interest in the world&39s second-biggest cryptocurrency by market cap from the bank&39s customers. He also announced that the bank plans to eventually launch cash-settled Ether options as well. Customers have been paying greater attention to Ethereum since the bank launched OTC Bitcoin options back in mid-March, which they now regard as somewhat of an investable asset class, as per the words of George Lewin-Smith, an associate who works alongside Goldman Sach&39s virtual assets team.
