Being bullish on Ether (ETH) has paid off recently because the token gained 60% in the last 30 days. The spectacular growth of decentralized finance (DeFi) applications likely fueled inflow from institutional investors, and the recent London hard fork implemented a fee burn mechanism that drastically reduced the daily net issuance.
Although Ether is not yet a fully deflationary asset, the upgrade paved the way for Eth2, and the network is expected to abandon traditional mining and enter the proof-of-stake consensus soon. Ether will then be slightly deflationary as long as fees remain above a certain threshold and the level of network staking.
