I'm saying this because it is real. Just imagine, Ethereum has built many tokens inside the blockchain and many people launched ICOs which most of them are totally weird and fake, but some of them are not. People usually like to trade their ethereum and turn it into a token where it can be determined as a "future asset" and it cannot be sold until they had listed on an exchange. The companies who launched the ICOs are usually selling the ethereum which gotten from their ICO in droves, in which it can make a dump on the Ethereum market.
This is a wrong assumption.
When the crypto market was bullish and ethereum went as high as $1,300, was ethereum also responsible for that?
Are other cryptocurrencies, such as, bitcoin, litecoin and so on, not collected during ICO as means of investment?
Are there no other platforms that also host ICO tokens?
Why then would you conclude that ethereum is responsible for the dump on market?
