112m people watched the Superbowl earlier this month, a sporting event known as much for its advertisements as its football prowess. One such advertisement was the floating QR code which tempted 20 million people to click into Coinbase's site within the first 60 seconds.

Coinbase was offering new investors $15 in Bitcoin if they signed up for a Coinbase account within 48 hours. Clearly an allure for many new investors, but accompanied by some concerns. Cryptocurrency is a very specialised field and new investors should be aware of the risks associated with it. In addition, you should always consider how this might affect your estate planning. You can't simply bequeath your cryptocurrency to someone in your will, so make sure whether it's your introductory $15 Bitcoin with Coinbase, or your millions of pounds with Ethereum, you've considered what you want to happen to it after your death, and how you can ensure your wishes are followed.
