Having created an account on Cryptster.io you get a free and secure wallet. Additional applications are not required. To start selling your cryptocoins you first need to send them to your wallet.
To do that, go to your Cryptster wallet. You will find it on the bottom of the menu bar on the left side of the screen. Inside, you will find the receiving address for sending coins to the wallet. When cryptocurrency goes to this address, it will appear as an INCOMING transaction. After the funds get 3 confirmations by bitcoin’s blockchain network, they will be available to you. The status can be viewed in the history of transactions.
Once you have funds in the wallet, you are all set to post offers and start trading.
