Probably because ETH is moving from a POW (proof of work) to a PoS (proof of stake) consensus algorithm with a minimum of 32 ETH required to stake, and a lot of people are buying it at these low prices so that they can start staking soon
But moving from pow to pos reduces the security and decentralization and therefore lowers the value of the tokens. The logical move would be to sell ETH if you own it.
PoS is a secure method and has been proven we have all seen this, this is a shitty argument. On the flip side I see mainstream investors knows of Bitcoin and Ethereum and also seeing POS as a dividend like system and this leading to an increase in investors buying.
