I didn't see the thread before it got changed to "deleted".
The text of the Tweet was:
"Best way to withdraw cash (without raising tax issues)

Now it is implied that the person is wanting to sell bitcoins, presumably after recognizing gains on those versus the acquisition cost but then cashing them out without reporting the gains as taxable income.
Without any context though, such as what jurisdiction that party resides, the answer will vary. There may not even be any tax consequences, depending on jurisdiction. It is unfortunate that this post was "deleted".
