Bitcoin simply can not physically reach the $ 100,000 course this year. At the level of 20 000 dollars, he still can and will rise. Further, he will not grow up in price simply because many willing to sell his bitcoins on a good course. You could see, as soon as bitcoin began to approach the course recently for about $ 10,000, he immediately rolled back. Many began to sell it at this price. So far, this will continue. People have partly lost faith that it will rise to a sky-high altitude and while its growth will increase the offer for sale until the situation is leveled.
