The main purpose of my comment is not about tracking funds, but on the ineffectiveness of the solution proposed by Tim regarding blockchain security.
You don't even have to split the stake, you can move them all to an exchange. Then, when you are ready,
- you deploy 20 witness nodes running your (malicious) hardfork version
- you declare 20 new witness accounts on the blockchain
- you move stakes back to an (unblocked) account
- you promote your witness accounts in the top 20
And tada, in less than 6 seconds, you get control of the blockchain! 🎉
