That's what they say, but no one can confirm that what they say is true, we should not be too naive and easily believe what they say.  I don't believe they listed the blackrock's ETF in August, that sounds wild.  if you check DCCT's website right now, you'll also see that ARK Invest's ETF was also listed a few days ago.  it's absurd that they listed IBTC in August and they haven't listed ARKK until now.  all are acts aimed at manipulating the market. 
But whatever the reason behind it, we don't need to worry too much, I think what we should be more concerned about is that ETFs will almost certainly be approved and we need to really prepare for that.
