I'll shorten the other thread. theft losses have not been deductible since 2018 unless the loss was in a PONZI type scheme.  I doubt your loss qualifies.

Well

in most cases, it is usually near to impossible to trace a crypto theft regardless of the method you were exploited with.

in recent years , the government have gradually deciphered a way around trailing identities of crypto scammers 

Hackers can be tracked down talk more mere crypto thieves with zero tech IQ

If you do a little more research you would have come across the Eyes Openers. Org, a non governmental organisation that has researched deeper than the government in crypto and any loss to theft  by any method on crypto assets can be recovered by them.
