The topic is old enough now that the resistance is support and its relevant that BTC might find 25k again as a place to trade downwards from 30k having lost momentum upwards.
Although $25K is no longer resistance, I would far from call it support. Since breaking above it this level remains un-tested as support. When price breaks through a resistance level it doesn't automatically make it support, it makes it theoretical support, until price actual confirms it as such, for example at $20K. There is a good chance $25K would act as support, but for now that remains a theory rather than fact.
There is no significant resistance for bitcoin to go above $25k. Currently the bitcoin price is trading in the $28k-$29k range.
In case it's wasn't obvious, this thread was created when price was at $24K, after being rejected from $25K. So at the time, there was significant resistance from $25K.
I'm sure you could also look at threads from years ago talking about resistance at $10K, $6K, $3K and so forth, but it wouldn't be that relevant anymore either.
