1. Third parties involvement: I personally prefer bitcoin to be sent and received peer to peer directly between wallets without involvement of third parties.
It depends on the taste of each person, if they feel safe to send bitcoin without third-party services, I think that's just fine. But still, I would advise you to transact through third parties to maintain the security of your funds.
2. Bitcoin should be a currency: We all know that bitcoin has been created to be a currency. But these days people look at it as an investment. BAKKT will keep us far away from the main purpose of bitcoin.
Back to first answer, it depends on each person's taste. Although many people make bitcoin as an investment, bitcoin will still be a currency and not an investment like stocks & gold. Moreover, the bitcoin market is a market that has high fluctuations, this is very profitable for investors. In the future, anything can change depending at that time developments and we cannot stop many bitcoin holders from continuing to aim at bitcoin, it is not possible because bitcoin itself is decentralized.
3. Regulations: BAKKT had been in negotiations with United States Commodity Futures Trading Commission. So, it will likely cause more regulations to appear.
I think there is no need to mention crypto regulations in the United States, because even if they don't exist, the rules will continue to grow in that country. The United States is known for its strict regulations but if BAKKT offers a win-win business, maybe the United States will consider this. Because what I see, the United States is more inclined into business.
