The news about Vitalik Buterin's death crashed Ethereum few days ago, when you have a large enough community you can manipulate the crypto market. One would be naive to think that the news about his death was just shared by someone without any reason.
Unlike bitcoin we know the person who created Ethereum. It was a deliberate attempt to bring the prices down so they could cash in. Ethereum went down to 200 USD soon after the news about his death was published.
The news proved to be fake and then we saw some resistance. At the moment Ethereum is fighting back as always and it is now above 250 USD.
When ethereum crossed 300 USD some people said its overvalued and over hyped and it is resisting price correction. Soon we saw correction and on that day Ethereum's price dipped to as low as 260 USD but then it rose again and crossed 300 mark.
After that it was hit by a flash cash disaster which crashed Ether again and soon after that the death horax of Vitalik Buterin but in spite of the misadventures it shows the resistance, it shows signs that it is a strong currency and by the end of this year it is likely that Ethereum would cross 500 USD.
