Here is another longish explanation of why ETF are not redeemable in the underlying asset in many cases.
https://bitcointalk.org/index.php?topic=252330.msg2715524#msg2715524The ETF isn't for us, we can already trade, buy, sell bitcoin without difficulty, and don't need to pay fees to get a paper contract instead of the actual coins. The ETF is for investors, large businesses, banks, institutional investors, people that want to sell bitcoin short and generally folks that won't have a wallet. Folks in this forum are probably never going to use it.
