Where to buy ERG?
ERG is available on centralized exchanges such as Gate.io, KuCoin, Bitmart and CoinEx, plus cross-chain routes such as Rosen Bridge depending on current liquidity. Spectrum Finance is a historical Ergo DEX reference that issued a sunset notice in 2024, so verify any active venue before trading. For self-custody, buy where available and withdraw to your Nautilus or Terminus wallet.

Is Ergo a good investment?
This is not financial advice. Ergo has strong fundamentals: fair launch (no VC dump risk), innovative technology (eUTXO, Sigma Protocols, NiPoPoWs), active development, and a cypherpunk ethos. It's a smaller market cap project with higher risk/reward than established chains. Research thoroughly, understand the technology, and never invest more than you can afford to lose.

How to provide liquidity on Ergo?
Providing liquidity on Ergo depends on the current active DEX or AMM venue. In general, you deposit equal value of two assets into a pool, receive LP tokens representing your share, and earn a portion of trading fees. Spectrum Finance is historical/frozen since February 2024, so verify the active venue, contracts, liquidity depth, and withdrawal process before depositing funds.
