I ended up saying yes for a few reasons, and with a few conditions. First, Bitcoin is a large and liquid market that struck me as less like an individual stock and more like, well, a market unto itself. Second, the strange process of buying, holding and selling Bitcoins is, itself, part of the Bitcoin story — and it seemed to me there was value in understanding it, and even writing about it, firsthand. Third, we agreed that the value of the holdings would be capped around $2,000, so I didn't see this as an investment meant to generate personal financial gain. Fourth, we agreed that the holdings would always be clearly disclosed.
