Don't worry.Because SG Scratch not tradeable for 8 years. So do you think they will change it ?
And yes You can 'only' trade it for 'SG Recycle Badges.' in Swap Shop.
SG Recycle Badges can be used to get pick tickets either on the current banner, or on a future banner if you hold onto them. If you only manage 30 rolls on this banner and don’t get anything you want to use, you can put those towards a pick ticket on another banner in the future.
Do not use any of these items unless you are 150% positive you know what you are doing. They are generally more useful to the average user as a Recycle Badge than as a booster.

BUT!! SG Scratch item have a good thing too.
It's this ticket.
that you can use '40 SG Recycle Badges' to get 'Awake Administer Ticket' in 'Swap shop'(This Ticket not have in NA at now)
This Ticket can use for "You can get 1 Item from AC or SG Scratch by 'Free!!!' by you not pay AC or SG point to Random it".That mean if you have something you want by not 'pay any money' to get 'Costume you want',You just keep playing and keep SG point to Random item from SG Scratch and swap it to become 'SG Recycle Badges' then get this Ticket and Keep for Free Fashion (But this Ticket can only get 1 Item per 1 Ticket,So before use it please think carefully.)
