No, Bitcoin has always been mineable at the same cost for everyone willing to mine while also enforcing a slow supply release. Premines offer free supply capture only for the central party that sells the premine, and oftentimes provides infinite liquidity allowing any wealthy party to capture the entire supply in a short timeframe.
