You can use (and bookmark) a custom url address to pre-select your coin, e.g. https://coinwink.com/eth (put a coin symbol after the slash).
You can place Coinwink app icon on your mobile device desktop. To do this, open coinwink.com on your mobile, click settings and then Add to Home Screen.
To create an alert you don't need an account or to click on a confirmation link. Your alert will be created instantly. You will receive a unique ID to your email. You can use this ID to manage your alerts.
Your email address will be deleted automatically from Coinwink database after the last alert will be sent. You can also delete your alerts manually - your email address and unique ID will be deleted also.
