Enter the desired purchase amount.
Click 'Buy' (Authorize if prompted)
When listing a new token, we highly recommend that you List & Buy in one transaction.
This is because when you list a new token, it starts at the lowest possible price. If you don't List & Buy in the same transaction, you might lose the opportunity to buy at the moment of minimum risk and maximum potential reward.
Locking tokens means you will be unable to sell or withdraw these tokens until after a certain amount of time passes.
Locking tokens shows your confidence in the long-term value of a listing. It shows future buyers you won't sell as soon as they buy in after you, reducing risk and making the listing more attractive.
Locking tokens will always be optional.
