To subscribe to CoinGecko Premium, head over to https://www.coingecko.com/en/premium. On this page, you can select your Premium plan and select a Monthly or Yearly payment method.
Cryptocurrency payment method is only available for Yearly payment. We use Coinbase Commerce and accept BTC, ETH, LTC, BCH, and ERC-20 version for USDC and DAI. Do not send non-ERC-20 tokens for USDC and DAI (e.g. BSC or Polygon). Coinbase Commerce will not accept these payment methods and CoinGecko will not be able to offer any refund for such mistakes as we do not receive the funds either.
