Can the money in the wallet be transferred back to the trading market?

I want to go to the wallet to earn points, and I can transfer from the exchange to the wallet. However, if I want to go back to the exchange to continue earning points, I haven't seen an option to transfer back from the wallet, so I ask all the experts: Can money be transferred back from the wallet to the trading market? If it can be transferred, how do I do it?

Also, I saw that when trading in the wallet, there is an option to use the exchange balance. Does this require an additional fee?
