The cryptocurrency market has always been known for its ups and downs. One year can bring record-breaking highs, while the next could trigger painful corrections. Investors often worry about entering the market during a bubble, only to see their portfolios lose value when the hype fades.
In 2025, cloud mining has become one of the most practical ways to reduce exposure to sudden market swings.
