Current account or deposit account

[lerelerele]

Some of the last hack news are making me think about a change in the timing of the transactions and the "no turning back" policies, if we could have 2 types of transactions (or bitcoins) one like now (current account and instant transactions) and other with a 24h possible to cancel transactions.

I want to make safe Bitcoins then i will send with the same address 100BTC and just after 2 satoshis, this Bitcoins are marked like deposit and if someone manages to make a transaction to try to steal, you have 24 hours to send 1 satoshi from the account you first arrived bitcoins to cancel the transaction.

What do you think about it?


Edited: Of course the receptor of the 24h transaction does not noticed about it in the first 24h.
