Is it possible to get IOTAs safely out of an address from which two or more transactions were made already? With safely I mean that there is no chance to get hacked if the third or later transaction is unconfirmed for a long time or invalid.
I have read about the Winternitz hash and the other threads about not making more than one transaction from one source address but I have not found a solution how to circumvent the problem if some funds are still stuck at the source address.
This thread does not provide a solution to the problem: What happens if I receive IOTAs at an address I've already spent from?
