According to economists, cryptocurrency is the mother of all bubbles. Though the skyrocketing prices in the bygone years and many experts pinpointing cryptocurrency as a bubble, it doesn't necessarily mean that it is.
In economics, a bubble is when the cost of an asset is more than its intrinsic worth. Usually, prices are gone up in a bubble when people show an extremely positive attitude towards an asset. When the bubbles burst eventually, people are left with nothing when they haven’t made a sale of the asset in the expectation of a hike in prices.
