There is currently a lot of speculations around "Bitcoin bubble." Many finance experts, bankers and traders do not believe in the bright future of cryptocurrencies. Partially, this is because of high volatility. At its peak in December 2017, Bitcoin price was around $20,000; later on February 2018, it was around $7,000. Now is fluctuating around $9,000. With a traditional stock market, when investors do not believe in certain assets (e.g. stock), they can go short against it.
