Owners of digital currencies must have some cold sweats these days. Bitcoin and its little sisters are going through a complicated period. Since the beginning of the year, the value of these financial assets has continued to plummet. Take the bitcoin, it somehow manages to stay above the symbolic threshold of 20,000 dollars. As for ether, it temporarily fell below 1000 dollars before rising slightly. We are therefore a long way from the record prices reached at the end of last year (around 67,000 dollars for bitcoin and 4,900 dollars for ether).
