What limits are on leveraging? What are your thoughts on this?
Leveraging just means that the broker is lending their client the most of the money to place a trade. The limits are set by the broker using their risk assessment, meaning that they have confidence they can close the trade out before the client doesn't have enough funds to cover their loss.
How will it affect the price? Why would any investor be interested in this?
Leveraged products aren't meant for investors, they are hedging and trading vehicles. There is a lot more to the ICE announcement on Bakkt that could influence price in a positive way but leverage doesn't really matter.
