At the end of the year the whole internet goes into list-making mode with lists for best movies, best TV shows, best songs, biggest political events and so on. I couldn't help getting into the spirit a bit myself, so here's my "Top 3" list of questions that clients and listeners have asked my team at Keen Wealth in 2017:

1. How much money do I need to retire?
2. How do I need to adjust my portfolio because of what's happening right now in the news?
3. What are Bitcoin and blockchain? Should I start investing in them?

I think we've done a good job covering the first two questions in previous episodes this year. So on today's show, I'm going to cross the final big question of 2017 off my list and talk about Bitcoin, blockchain, and cryptocurrencies – definitions, pros and cons, broader applications, and what moves, if any, you should consider as an investor.
