Hello im new user, requirements to get more free storage ?
Find someone willing to host for you gor free or learn to selfhost on your own device.
There are no requirements beyond those of whoever offers you Nextcloud, since there is no specific place that hosts Nextcloud.
If your goal is free storage you can also consider a service like Mega. Closing this topic so the goal is this chat is to support people running Nextcloud on a more technical level rather than finding free storage from others. Cheers.
