I suggest you re-read Saltynuts' post.
He said XIV is bust. This is a fact. XIV has had an acceleration/termination event. It is bust, finished, gonski!
SVXY, although smashed, has not had a termination event this time. It is not being terminated. It is not bust. Whether you should buy and hold it like a dufus is another question, but it is clearly not bust/terminated.
Get your facts right.
Unable to "connect the dots" on partial question. "better choice than what for what specific strategy?"VIX option didn't get busted, so better choice?
