Base God (TYBG) is a community-driven meme coin on the Base platform, with no team and roadmap, with a maximum supply of 125 billion coins, close to fully diluted, with price forecasts ranging from $0.00005 to $0.001. Most expectations in 2025 are in the range of $0.00005–$0.00007. It is aggressively predicted that it can reach $0.000414 in 2030 and may reach $0.00147 in 2040.
