I used to think crypto had some sort of use case. Here's some questions that might help:

Why did a new money need to be created for this to work?

If a blockchain needs an Oracle, why does the Oracle need the blockchain?

Who gets the final say over what this crypto is or how it will work in the future?

What is the functional difference between:

robux as it is now with an SQL database,

robux if it were to use a blockchain instead, but only the roblox cooperation can run the servers that host said blockchain,

robux if only shareholders of the roblox corporation could run SQL servers for robux accounts,

robux if only shareholders could run a blockchain,

robux if anyone can run the servers that host said blockchain but the roblox corporation decides what software gets to be robux and can still freely create new robux,

and robux if the roblox corporations software to run robux was arbitrary and up for debate if that was actually robux or not
