Thank you guys, I've probably lost in total 70% of my total BTC to sites like this... makes me feel a bit sick just thinking about it, and how stupid I've been by not learning my lesson

The EveryDice owner at least was a good guy and kept in regular communication with me, and I did get my remaining invested amount back (even though it was a small fraction of my total investment after 1DiCe hit them) - I haven't given up hope on these sites either, though I'm not getting any communication from any of them.
I had invested 22 BTC total deluxeCITY - I lost around 10 BTC to mateo but the remaining amount is still invested and it won't let me divest.
