It's not any real change IMHO. They just don't want the contracts to cost a quarter mill with no granularity. So it could increase their volume a little.
I also have been at least somewhat dubious over the years that the CME futures tanked the BTC price in 2017... Maybe contributed? A catalyst?
Derivatives steal volume from the underlying asset class and therefore if nothing else they act as a cooling mechanism.
Agreed. And the positive side of that is less volatility in the underlying asset. This was the reason for them to exist in the first place so you can hedge a position in the actual asset. They are a form of financial insurance.
I am agnostic as to the +/- of derivative futures contracts.
I do not consider losing volatility as positive in a deflationary asset.
Lack of liquidity forces higher prices, period not matter how they want to argue it.
