The most popular ETF registrant pulled their registration because the government was closed down and the clock was ticking so they didn't want it to expire while the government was closed. They have recently resubmitted their registration. This restarted the time clock for a decision so this may delay the acceptance of this ETF but every piece of info was leading to a highly likelihood of acceptance this next decision point.
The BAKKT network created their own delay as they felt they were not ready back in December with their new network. They announced they have completed the changes and are now ready to launch. It is scheduled for the end of February but again, it needs SEC approval for this new exchange. This one should go through without a hitch and I expect a notification any day of the approval. I think Bitcoin will have a substantial spike on the announcement of the approval for BAKKT.
The Fidelity service starting in March will just be an extra launching pad. Hopefully, bitcoin will be back around $6k when Fidelity services start and shoot up from there.
