Sept 9 (Reuters) - Winklevoss twins-backed Gemini raised

the proposed price range for its U.S. initial public offering on

Tuesday and is now targeting a valuation of up to $3.08 billion

in its listing, reflecting investor interest in crypto ventures.

The cryptocurrency exchange aims to raise $433.3 million by

selling 16.67 million shares priced between $24 and $26 each.

This compares with its prior proposed range of $17 to $19 per

share.

Gemini expects to list on the Nasdaq under the "GEMI" ticker

symbol. Goldman Sachs and Citigroup are the lead bookrunners on

the deal.
