SEC has until Feb 24 to approve or reject Winklevoss bitcoin etf...if COIN etf is approved...price will automatically double to $2,000(SEC approval means bitcoin is a legitimate asset class)...
If the Winkelwii ETF actually manages to list itself in the NASDAQ, then there will be some effect on the Bitcoin exchange rates. But don't expect the market cap to increase by $16 billion all of a sudden. Be patient.
