I have.

I'm not saying I've made enough to buy a house and a new car or anything.....so don't get the wrong impression. LOL

I only play poker really, on various sites. Yes I have made some nice pocket change from it. Yes I have lost some too.

In the past couple weeks I've made about 100 bucks playing poker here and there on some micro tables and $25 GTD's on betcoin.
For example, a couple days ago I took the $25 GTD (.50 cent buyin) for first place and it paid out $15 in btc.

Are you asking because you are unsure of the bitcoin gambling community being legit or not?
If so, you just have to be wise about where you deposit, and do research before you start going to a site.
Most well known legit and trusted bitcoin gaming sites have a good community following from here, to their forums.
IMO I trust betcoin and nitro most and love playing there. I also tool with Bitcasino and their live poker (and sometimes Roulette) its fun!

If you want to try perhaps poker or anything, look for sites that offer freerolls. It allows you to play for free, try their platform out, risking no money - and if you win the freerolls you get to keep the BTC.

Good Luck!
