 When iterating (incrementing) query ID, it is cheaper (in terms of TON spent on fees) to iterate through bit number first, and then the shift, like when incrementing a regular number. After you've reached the last query ID (remember about the emergency query ID - see above), you can reset query ID to 0, but if highload's timeout period has not passed yet, then the replay protection dictionary will be full and you will have to wait for the timeout period to pass.

 ## Conclusion
 
 As you see, there are many different versions of wallets in TON. But in most cases, you only need `V3R2` or `V4R2`. You can also use one of the special wallets if you want to have some additional functionality like a periodic unlocking of funds.
