According to specialist researchers, Crypto Fund Research, more than 70 hedge funds specializing in investments into digital asset projects have closed this year, Bloomberg reports. The majority of the closures identified came from North America and Europe, with 28 and 23 respectively. This trend runs contrary to recent research from Fidelity Investments that suggested institutional investments in cryptocurrency were likely to increase over the coming five years. Investors are reportedly nervous about venturing too deep into the cryptocurrency market because of its volatility and lack of regulation. As governments look to clamp down on digital asset projects from tech giants like Facebook, the future of cryptocurrencies — from an institutional perspective at least — looks increasingly uncertain.
