Premining

Premining is the process of mining or allocating a cryptocurrency's coins by the project developers before the blockchain is publicly available. Premined coins are held by the team from the moment the network launches.

Legitimate uses

• Development funding — a premine can finance ongoing protocol development, audits, and infrastructure without relying on venture capital.
• Foundation reserves — some projects allocate a portion to a non-profit foundation for ecosystem grants.
• Team compensation — tokens may vest over time to incentivize long-term contribution.

Why premining is a red flag

A large or undisclosed premine concentrates wealth with insiders from day one. Common problems:

• Dump risk — developers sell their premined holdings into the market, crashing the price.
• Unequal starting position — regular miners and buyers start at a disadvantage.
• Lack of transparency — if the premine size is hidden or revealed after launch, it indicates bad faith.

There is no universal threshold, but a premine exceeding 10–20% of total supply is generally treated with skepticism by the community.

Fair launch

A fair launch is the opposite of a premine: the coin is released to the public with no prior allocation to developers or insiders. Bitcoin is the canonical example — Satoshi mined the first blocks alongside the public, and no coins were pre-allocated. Fair launches are associated with higher community trust.
