Update 180331: The YouTube information dropped substantially. This is an indication that the interest and enthusiasm dropped on a global scale. The price of BTC and other cryptos like Ethereum dropped again. When Bitcoin goes down, everything goes down. Ethereum (ETH) is a major crypto that drives the ICO market, it is a ICO platform where smartcontracts and tokens can be created quickly. In the last periode of March, major social media companies (Google, Facebook, Twitter) are or will be blocking ICO advertising. Also MailChimp will take action. If you promote cryptos, you account will be blocked. This process of blocking new ICO’s is called the ICO lock. More on this later.
