CoinGecko is a crypto data aggregator, not an exchange or wallet services and we do not buy/sell any cryptocurrencies. You will not be able to deposit/withdraw any funds onto our site.
The portfolio feature is NOT a wallet.
It serves as a one-stop platform for users to track their crypto transactions/ holdings, including their total balance, profit/ loss, transaction history. It also allows a filtered view of all the favourite coins you are interested in, allowing you to track their data easily.
