Ok, I might have some difficulty explaining the concept, but the background for this is simple. Let's say the US SEC wants to make sure that global Bitcoin exchange prices cannot influence the Bitcoin price in their regulated market, would it not be easier for them to just allow price determination based on trading prices within exchanges that adhere to their regulations?
Let's say, they can introduce specific guidelines with rules that needs to be adhered to for exchanges to be included in their market and for price determination. If exchanges adhere to these requirements, then institutional investments can be based on your exchange trading volume, but if you do not adhere to these requirements, your exchange price will be ignored?
Can a separate market like this, help to reduce Bitcoin price manipulation for local markets that wants strict control over price manipulation and can they operate independently from a global Bitcoin market?
Ps.. I am not a professional trader, so my lingo might be wrong, so I hope you can understand what I am saying. Merit goes to the person that puts this in a post that explains this with the correct terminology for everyone to understand.
How does this reduce manipulation of prices?
Doesn't this further increase the potential for prices to be manipulated, since your proposal would essentially mean that SEC is the sole determinant of what exchanges are allowed to be included in this so called "price index", and which ones are ignored? If they wanted to, they can remove any exchange that they don't want from this index.
Also, who says that the market will actually adhere to the price index, as opposed to still buying/selling at the best rates, even if that means that they are using an unregulated exchange?
I really don't understand where you are going with this, nor do I see a point in a central entity publishing any type of price index that filters out unregulated exchanges. Plus, wouldn't arbitrage opportunities arise which lead to prices eventually levelling anyways?
