The exponential age demands new solutions and investment tools. One of the emerging trends in the financial industry is the growth of the new class of assets in the digital world, i.e., the massive growth of cryptocurrencies. Cryptocurrencies are new building blocks of financial services, and investing in these emerging classes is impossible for the public as it demands some special knowledge and skills. Investing in cryptocurrencies is more sophisticated than the traditional stock market, and ETF-based passive investing is not established yet. Innovative companies such as Optifund provide affordable solutions for retail investors.
