Crypto backed data storage – pay once, store forever

It's a fundamental law of nature. Anything being sold as "forever" or "unlimited" is being sold on a lie.

Also, in this particular case, that generic "Product of the Week / 1st" badge on the page that doesn't even bother to link to a pay-for-your-award organization just screams "scam".

Forever*

*For as long as the service remains profitable and the owner cares to run it.
