The mining company Riot Blockchain has a market capitalization of $4.01 billion. It has had a very successful autumn. Shares have increased by nearly 150% from the September lows to the November highs. It is not surprising that a correction occurred in December: the securities fell by 7.75%. Additionally, the growth of BTC has slowed down, which naturally affects the profits of the company that engages in cryptocurrency mining. Nonetheless, Riot plans to continue increasing its bitcoin reserves. To this end, the company recently issued convertible bonds worth $500 million. This move may help strengthen its position in the market.
