Bitcoin is the oldest and best-known cryptocurrency, but other digital coins are also increasing in value. The reason is statements by the chairman of the US central bank, Jerome Powell, about a cautious policy. This could indicate a period of stable interest rates, making risky investments – such as crypto coins – more popular.
But speculation about approval by the American regulator of a fund that tracks bitcoin is also causing the price to rise. Earlier this week, an erroneous message about such an approval caused a price surge above $30,000.
