In my opinion, an ETF will do for bitcoin what ETF's and Options have done for gold and silver. It makes them able to be manipulated. Last time I heard, all the world's above ground gold, TIMES FIVE, is traded on PAPER every day.
As it is currently, bitcoin is sheltered from such manipulation. Fact: If one person wanted to buy a billion dollars worth of bitcoin, they would have to find someone willing to sell 950 bitcoins today, then find someone willing to sell them 950 bitcoins tomorrow, and continue to do the same for 2.7 years.
Those kinds of sellers don't exist. I am a seller and I would not want to raise those kinds of eyebrows by selling quantities.
No matter how you slice it - Soros, Gates, and other low life scum have no better chances than we do with bitcoin.
