Decided to give BitFortune a try today because of it's Amatic slots selection.
That's the first plus for, I love the Amatic slots, but many casino's don't offer them or only offer a limited selection. It seems BitFortune has them all!
I love the Amatic slots for their big bonus rounds and colourful graphics.

I did a 0.5 BTC deposit and opted out for any bonuses. At first I was confused, because suddenly my deposit address changed and I didn't see what happened to mine. Luckily I got the 1 confirmation quickly and the BTC was credited.
The second 0.5 BTC deposit I noticed a small popup so that was more pleasant.

The site itself is quick, registration is easy and the site has a custom design. Find the games you want is easy because of the filters.

After a 3rd 0.5 BTC deposit I managed to get up to 3.3 BTC. I started a withdrawal and here are we getting to the first downside of BitFortune. It simply creates a "pending" withdrawal, which is all fine, since it's quite a big amount (I haven't tried with a small amount to see if it's instant).
When you initiate a withdrawal your balance is still available for playing. Unfortunately I got tempted and played and my balance went down to 3 BTC.
I had no ability to cancel my 3.3 BTC withdrawal and now I also have a 3 BTC withdrawal pending and now a few hours later even a 4 BTC withdrawal pending. This is a huge downside and very unclear.
Unfortunately the only contact method is a form and an email address, no live chat at all. I'd really recommended for this to be implemented, even if it isn't 24/7.

I hope this feedback is useful and will update the post when I retrieve my full withdrawal.
