Why am I asking is if there actually is a relation between miner interest and price I think there will be great opportunities to invest when Ethereum's EIP 1559 is released and miners will have to shift there attention to other coins.
Miners mine cryptocurrencies (Proof-of-Work, PoW) to sell their rewarded mining coins to take profits after pay their power bills. They will stop mining if they don't have reserved budget to pay power bills or don't see future for higher price.
Stakes buy cryptocurrrencies and staking (Proof-of-Stake, PoS) to have the same things.
People feel with EIP 1559, the transaction fees on Ethereum network will be cheaper and makes it become usable for non-rich crypto investors and users. It can be true or not true, let's wait for real results on chain.
Miners and stakers can impact the price. If they are whales, they can manipulate the market.
