Should I open a checking account now?

Question

Electronic accounting

There was a problem. There is an IP and you need to connect payment systems to the site. Payouts will be instant. For this, it is planned to connect Yukassa and qiwi. It costs me a lot of money to connect a current account. Is it possible to do this without settlement accounts and will it be more difficult to report and will it be more expensive in general?
That is, the site works on the principle of putting money in and it lies there. They can be withdrawn with a fee. At the same time, earnings for intermediation and for services, and as a result, without a current account, is it all impossible or very difficult to take into account when depositing / withdrawing, or does anyone care at all and, most importantly, income?

Answer 1

I understand what's going on!!! I ran the code from Rider, and there is my own console. When I ran it from a regular console - no errors and the cursor moved.

Answer 2

obviously: System.ArgumentOutOfRangeException: Value must be positive and below the buffer width.
Parameter name: left
is clearly out of bounds
PS: positive is something more than zero
