UK Visit Visa Bank Statement Monthly Income, should I put all the salary and withdraw my expenditures or I can only deposit my savings?

My monthly salary is 650 USD which I receive in cash each month (transactions in my country are mostly cash-based)

I know the ideal bank statement would show a deposit of 650 USDs payday and a withdraw of 200 USDs during the month, so the net saving would be 450 USDs each month.

But I am, due to logistic purposes, planning to directly deposit the net saving (450$) each month at payday with no withdraws and explain in my cover letter that this account is only a saving account for the UK trip

Do you guys thinks that it is okay y TY o do that?
