Question is, at what volume to we start to take these prices, let alone the 'ETF', seriously? Not Joking
If someone is willing to pay $400 for 10BTC (100 shares) with the market at $226, who gives a shit? He's an idiot
1000BTC? Still a fool
10,000 BTC? Start's to look a bit more sane, but still stupid
etc ...
Point being, unless there is a significant $/BTC volume of transactions the price is meaningless, and just another tool to be used to potentially mislead people. If there is no significant liquidity pool and turnover, it's like BTC, except you don't hold it yourself, have bigger spreads and higher slippage. Where do I sign?
If it's a raging success I will totally own being completely wrong, but I have serious doubts that this little experiment will have a positive impact on the BTC price and is more likely to lead to bad news than good.
