Hello,

Could someone explain to me what happened with my Blackcoins because now my wallet is empty and I am pretty sure I used to mine such coins around 3 years ago!

Was there an attack (how convinient that it happened with so much crypto currencies I used to have) causing a new blockchain?

Thanks in advance!
My wallet is BHxGFDy5Dx6JSceHkD1wpBfveiUUYgaZc1 but it doesn't show any transactions here

https://chainz.cryptoid.info/blk/search.dws?q=BHxGFDy5Dx6JSceHkD1wpBfveiUUYgaZc1

The address seems to exist but has no coins in it and also was never used.

Are you sure you have your original wallet.dat?
If you are sure you used blackcoin already, then you most probably have installed a fresh version of blackcoin and thus created a new address.

According to the blockexplorer you haven't been hacked, the address never had any transaction and thus also wasn't emptied.

Try to find your old wallet.dat, BACKUP IT, then replace the new one in your %appdata%\Blackcoin with the old one and start the client to have it sync.
