A nice scam.
How is it a scam? Nobody is required to pay more than NAV if they do it is because they believe the asset will rise and thus the premium paid is just the cost of getting into a position now rather than waiting. Slippage happens on exchanges is that a scam? Price is currently $91.08 and you believe it will fall. You can sell 100 BTC @ $91.08 but selling 500 BTC will drop the price to $90.98. You are getting less than if you sell slowly, then again if you feel the price will fall below $90.98 before you can unload all 500 BTC @ $91.08 the premium paid for fast execution is worth it.
It would be like saying selling BTC for x on MtGox and buying it for y on BTC-E when x > y thus collecting a profit of x-y is a "scam". It is called abritrage. The fact that new shares can be issued or redeemed is what keeps the price inline with the underling asset.
For future reference ... just because you don't understand something doesn't make it a scam. Many people call Bitcoin a scam using the same "logic".
I perfectly understand what an ETF is and how it works.
It's garbage, a worthless piece of paper, one of those "financial products" or "derivatives" that add nothing meaningful to the economy.
If you hold your private keys, you are holding the real thing. You can redeem them everywhere, no matter what. Bitcoins was born to be a trust-free, decentralized system to transfer and store value, and you have no need to trust the Winkle-evils to hold on your Bitcoins. How do you know that they are not issuing more shares than Bitcoin they hold? How do you know they won't file bankruptcy? How do you know you will be able to redeem the value their pieces of paper are supposed to have? How do you know their Bitcoins will not be stolen?
You don't know, you just buy a piece of paper that represents some Bitcoins that supposedly a third party is holding for you. Wow, genius, I guess Satoshi created Bitcoin precisely because he was in deep love with these amazing "financial products" based on
promises that spread so much wealth between people. How could we survive without them?
It's just another form of debt, and thus essentially a scam. Everybody should man up and hold onto the real thing and throw away that useless paper issued by some guys who have never done anything in their lives (except suing Facebook, what genius entrepreneurs they are).
That said, these could be bullish news if the retard twins succeed. A scam, but bullish for BTC exchange rate. Just do not forget that these derivative crap has messed up the whole economy. I know for sure I won't touch one of those toilet papers with a bargepole.
