According to CoinDesk, Oliver von Landsberg-Sadie, CEO of BCB, a financial services group focused on digital assets, said that the bull market in 2013 was driven by technical experts and the hidden network. The bull market in 2017 was a burst of speculative retail investors. The event was triggered by the growth of the financial sector in 2019, which is diversifying the old portfolio and eventually having a professional mechanism. In the UK alone last month, nine banks and over-the-counter (OTC) financial institutions were included in the BCB. Landsberg-Sadie said that this has increased the number to 32, most of which was added this year.
