Nothing launched now will have much take up. Interest is dead. I expect this to see a major uptick in a bubble just like everything else.
I don't think interest is still completely dead. I still see plenty of people talking about it. Since people seem to care more about its actual approval rather than what its approval will bring to the table, it's still likely to cause a spike, which in turn may trigger a bull run. The market will be running on hype like it always has.
Whatever though, I still don't believe any Bitcoin ETF will be approved anytime soon.
