Stellar Lumen (XLM) reached an all-time high price of $0.88 on January 3, 2018, but its all-time high market cap of $18.366 billion only came three years later, on May 16, 2021, at a price of $0.71, due to the token’s supply inflation. XLM had a market capitalization of $17.55 billion in 2018, during its ATH. Stellar has an unpredictable circulating supply inflation. All XLM in existence were created by October 28, 2019, according to the project’s documentation, but there are still tokens under the ‘Stellar Development Foundation (SDF) Mandates’, or in both the ‘Upgrade Reserve’ and ‘Fee Pool’, that can be added to circulation at any time.
