Bitcoin's growth began in early 2017 and then it touch 20000. Bitcoin's largest growth is due to the ability to trade with tether dollar. With this growth, a huge growth in ICOs appeared. Nowadays about 30 ICOs are added to the market. This huge volume of ICOs, has taken the power of bitcoin growth. Like weeds next to a tree. Bitcoin will not grow until ICOs exists.
At the other hand, when there is weed next to a death, there will be competition between them, and if the weed is not there, the growth of the tree will be less competitive. I don't really think its the increase of ICOs that is the cause of bitcoin not going to reach that heights. 2017, bitcoin strock a point that was not expected, no one knows what it has in stock for this year.
