Instamine
A launch pattern where an unusually large share of supply is mined very early, raising fairness and concentration concerns.
- Also known as
- fastminepremine
An instamine occurs when a large portion of a cryptocurrency's eventual supply is mined shortly after launch, often before most potential participants can join. It differs from a premine because coins are produced through mining, not directly allocated before the chain starts.
Causes include low starting difficulty, slow difficulty adjustment, software bugs, hidden launches, unclear release timing, or deliberate launch design that advantages insiders. Even accidental instamines can create long-term trust problems.
Instamines can concentrate supply, distort governance, reduce public trust, and create selling pressure if early miners control a large share of coins. Communities often audit early blocks to evaluate launch fairness.
