Similar to the above-mentioned hedge funds are interested in crypto currency and are beginning to recognize its management companies and households. Not so long ago, there was news that a management company in the United States had opened an investment bitcoin fund for its customers, which made many interested in it. This happened in 2016. This asset class is completely new - just a couple of years ago it simply was not. In that fund, the maximum amount that could be invested to one client - $ 50,000 was set. This is a rarity, because you can not find an organization that would set such limits on the size of the contributions of its members. But, in our opinion, this method is the simplest in terms of risk control. There simply is an allowable amount that can be lost, and the contribution is limited to it. Investment companies often complain about the short-term focus of their clients. But such a focus becomes clear when failures in investment issues can adversely affect their lives. Nevertheless, all available for investment places in the funds were sold in a short time.
