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.
in my opinion, because it is not regulated, people who control money are scared about the entire crypto society... just because they can't control and they can't track it
they will create negative conditions for the investors until get it regulated.
