Why should we happy with that?
I believe this whole quote in that article is dead wrong:
"We imagine LedgerX won’t have too difficult of a time moving inventory, considering bitcoin’s astounding run of new record highs persists unabated. In a market starved for volatility, giving the "big boys" the ability to trade with massive leverage on what is already the most volatile asset class in existence is just what some funds need to make their year as they swing for the fences with 20x (or more in) margin."
From the rulebook rules that I last saw, LedgerX does not allow any margin trading. And no shorting.
