Linode can be a great alternative to traditional hosting providers like HostGator, GoDaddy, and 1and1. However, like any other hosting provider, Linode does require a credit card to sign up. This is to ensure that Linode has sufficient funds to cover any potential server failures or other unexpected costs. In the event of a credit card failure, Linode will work with the cardholder to get a new card or refund the money.
However, there is no guarantee that this will happen. If you are concerned about using a credit card with Linode, we recommend looking into other hosting providers.
