Warning` Switzerland’s largest bank, UBS has warned of a crypto winter where prices crash and may not recover for years. The bank’s analysts, led by James Malcolm recently explained in a note to clients several reasons why cryptocurrency may lose its attractiveness to investors this year. The UBS analysts detailed that the Federal Reserve’s interest rate hikes are set to reduce the appeal of cryptocurrencies, such as bitcoin for many investors who see the asset class as a good alternative store of value.
