Indeed it is how blockchain works within crypto currencies. I find it interesting that many participators (i.e. OP) don't understand how unsafe their coins are and this has to be explained as such by the commentator. Admittedly, perhaps not everyone finds interest in the same things as me.

Except that this has nothing to do with being "unsafe".

OP used his private key/mnemonics somewhere else and that's equivalent to giving your bank account + password to other people and then complaining when they take your money.
