Every week a Guardian Money reader submits a question, and it's up to you to help him or her out – a selection of the best answers will appear in next Saturday's paper.
This week's question:
A friend says now is the time to buy shares in Bank of Ireland as they are €0.28, down from a high of €11. He says people who bought Barclays in 2009 tripled their money. What do readers think? Can I – should I – profit from Ireland's woes?
What are your thoughts?
