Hello,
I'm getting the same warning from one address I've only used to collect mining profit from different pools. How can this be possible??
Thanks for any info on this,
Orphaned blocks.
Could this be related to the supposed hack that Eligius was victim of?
No.
And as far as I've heard, Eligius has not been hacked. They just had a miner that was contributing hash power to collect when the pool found a block, but throwing away the blocks that the miner solved
how does that affect me?
It probably doesn't.
can I loose btc I currently have there?
Where? At Eligius? It's always possible for someone to run off with your bitcoins if you give them control. Perhaps you should consider withdrawing to your own wallet so you have control over the bitcoins.
