pleast, take a look at how much ethereum that already purchased in 2017 compared with this year or last year. Ethereum gets its ATH due to the majority of ICOs made its platform that available that only used ethereum as the main payment but this time it looks so different.
it is one of the factors that makes ethereum grow slowly. because many projects with the ethereum network platform failed, and that made adoption of ethereum less. even though there is a good IEO now, the growth is also different. even the binance launchpad uses the BNB for their sales. several exchange platforms where the IEO now uses their coins to grow.
