Satoshi was truly brilliant in how he designed the issuance schedule. Mining the coins too quickly would have centralized them, mining them too slowly and a centralized organization could have taken over the mining process.
Having 97% of the coins mined in 15 years allowed for them to become truly decentralized and owners of the coins now will continue to decentralize them as they spend into the market for goods and services. nostr:note1a97lm0u8ak666kqjpz59e59qzpdtnl4tjx849uj0xv399mluvqgskchsvs
