London financial expert, CEO of NEX Group, Michael Spencer, was among those financiers who consider Bitcoin a bubble. Nevertheless, he believes that the price of Bitcoin will reach $ 20,000, and only after that, it will sharply go down. In an interview with Guy Johnson on Bloomberg TV in London, Spencer said he had no idea if the Bitcoin price would double before it halved, but noted that the $ 20,000 level could be reached "damn fast." Johnson called the growth of Bitcoin, which exceeded the $ 11,000 mark last Wednesday, "irrational."

As expected, Bitcoin quickly played his position and even set a new high at $ 11,845. This was promoted as official news that the US regulator allowed the exchanges to sell futures and options for Bitcoin, as well as rumors that NASDAQ is also going to launch Bitcoin futures next year. Later this rumor was disproved, but managed to manifest its influence. Now Bitcoin continues to bargain at the borders of the new border of 12 000 dollars, and most likely with the beginning of the week it will pass this level. At least there are no weighty reasons that could prevent this. Capitalization of Bitcoin closely approached the mark of 200 billion dollars, and the total capitalization of Cryptocurrencies exceeded $ 350 billion.
