The warnings (first paragraph) are standard and all perfectly true, and the advice to stay away from bitcoin (last bullet) is good advice.   Bitcoin is a risky investment, mining is lucrative only for well-planed operations, and even experts find it difficult to protect their coins from theft.  People who do not know how computers work should not be pushed into it.

As for the ban on bitcoin-related transactions, it is an abuse of their power, but what did bitcoiners expect?  "Hi, we are your friendly bank, I understand that you want to destroy us, what can we do to help you?"
