BAKKT is backed up by the biggest banks in the world, and the biggest stock exchanges in the world.
What is BINANCE backed up by? Themselves? Bitcoin? 1's and 0's? "Fantom"? haha.. that name, Fantom sounds childish and untrustworthy by nature. I mean really, their company controls BILLIONS of dollars, daily. Also Binance is not exactly winning over the hearts of many USA trading clients anymore, come September... By the way, I admire Binance a lot but I am still going to tell it like it is.
CBOE was a major player too, but their Bitcoin product quickly fizzled out and they left the market. Not saying that'll happen to Bakkt necessarily, but their success hinges on deep pocketed institutional interest.
Binance, Bitmex and similar loosely regulated grey market exchanges will continue to thrive on retail traders and lower tier trading operations. But if they ever start enforcing mandatory KYC, we'll see how much interest is left.
