Ive been using freebitcoin for a while too, but it's meh, never won anything cool
very interesting articles, this one with pennsylvania lottery shocked me. The problem with scams is huge, and looks like we're going nowhere to make the situation better
Recently i've found
CryptoGamble - they've got some interesting lotteries there.
I've checked it, you intruiged me, and from what i can see, you can use Bitcoins and Ethereum there, hummm... And some
scratch games too...
