Secure your ETH ASAP !
And here I am again at it : talking about ETC ( Ethereum Classsic )
Why ?
Because I want everybody to know what they are in for.
I have explained some things in my previous post :
https://steemit.com/cryptocurrency/@cryptoninja/the-ethereum-classic-madness
What I have NOT said is the WHY - "All users who had an Ethereum balance at the moment of the fork now have a matching balance of ETC " - is a risk... for everyone making transactions on the ETC blockchain.
In crypto tehnology "spending" any amount of your coins requires a key that is kept secret ... until you send that coin to a new wallet , effectively spending it.
OK , all ETH coins you have not moved/spent since the fork are at risk until you send it if you spend any ETC that belonged to the same address on both Blockchains - ETC and ETH
Basically - If you have sent 1 ETC from a wallet containing both ETH and ETC , from the Hard Fork , the key you have used to sign that transaction can theoretically be reused to send all the remaining ETH from your wallet by anybody.
What you need to do ASAP if you are in the ETC ( Ethereum Classic ) game - resend ALL your ETH ( Ethereum Hard Forked ) to yourself to effectively create a new key that is not also on the ETC chain.
I hope I was of some help !
