EIP-1559 is a proposal for Ethereum that will be released on August 4th. This is the first step in ETH2, and the shift to Proof Of Stake. In essence, it will make gas fees more consistent and predictable. This is necessary because it will allow users to predict their transaction fee more effectively before sending.
Another aspect of EIP-1559 is that it will burn the gas fees, making ETH less inflationary. This is a big deal for holders because less coins will be available for miners to sell, therefore the circulating supply will be diminished. This is a good thing for your ETH because a lower circulating supply means a higher price per coin.
