also you lastly say white wash coins by moving them to different wallets(facepalm)
if you are re-orging blocks then any attempt to move funds gets undone when you the reset the blocks that moved the coins..
you cant just hoard coins and delete transactions because(let this sink in) the transactions is where the coins are.. they are not stored separately in wallets

your wallet does not store coins... your wallet just stores the signing key
if your resetting the transactions your resetting which addresses have the coins
