Can you or can you not sign a message from an old address?
No, I cannot as I mostly convert the crypto to fiat and used different address. Still I can sign one from the recent one from which I signed a message already.

No
Actually the trust might be appropriate given your statement, given the posting gap and you labeling yourself as a BM (while making such statements).
There are many people here who have posting gaps that does not mean they should get a red trust on the basis.
