According to online reports, Swiss National Bank President Martin Schlegel said on Friday: "The market liquidity of cryptocurrencies during crises will be questioned, and their high volatility is also a major risk to long-term value preservation. In short, it can be said that cryptocurrencies have not yet met our high requirements for reserve currencies." He made the above statement in response to a proposal by the advocacy organization Bitcoin Initiative to increase its holdings in Bitcoin. According to research by the organization, if 1% of investment is allocated to Bitcoin in 2015, the overall return of the SNB will almost double, and the volatility will only increase slightly.
