Bitcoin may have piqued in terms of value and public interest in 2017, but the cryptocurrency has been far less popular this tax season. According to a recent report, fewer than 100 people have reported bitcoin holdings so far. The figure, reported by CNBC, comes from Credit Karma, a popular financial app through which people can view their credit score and file taxes. Of the more than 250,000 people who have filed through Credit Karma this year, a whopping 0.0004 percent have claimed to have money in bitcoin or other cryptocurrencies.
