As a user on ROBLOX I get robux sometimes and it is really hard for me to save my robux because I am the type of user to spend most to all of it in one day. I think how it would work is you could deposit and withdrawal a certain amount of R$ into and from your savings account at any time. If ROBLOX were to add this feature it would change the way I spend my robux, and even if I spent most of it in one day I would still have some left in the savings.
