Instead of many small transfers, you can pool cash from multiple accounts (A to B to C) before making one final transfer to your account. This minimizes the number of connections you need to scrub, reducing the risk of a trace.
This is the most popular way to get rich. You must find an account with a high balance (often found during "Trace a Balance Transfer" missions), transfer the money to your own account, and then meticulously delete the transfer logs in both the target's statement and your own to avoid being caught.
You can use Cheat Engine to find the memory address for your current balance and change it to any amount.
