I played on the 1xbit before I think multiple times due to the huge variety of games and types of games they are offering and I redeposit again later today so here's my review based from today and previous experience.
1. First I would like to point out that they are paying and they paid my request withdrawal but I think still depends on the situation and the behavior of the users. Some users if I could remember would be needing to undergo a KYC verification.
2. It's good to have a lot of coin choices to avoid high transaction fee, they have a recommended coin which is XRP probably to avoid ridiculous fee of the ETH and BTC.
3. Just like the common downside of the 1xbit, there's a lot of options that makes it really confusing and one by one you need to figure out "what's this button do" though having a lot of features is good but too much might become a negative especially to players.
4. Bet delays on live bets I think it is around 2-5 seconds? Well it's acceptable for me.
5. Security is through email and 2FA I think it would be much safer if they would add a anti-phishing code or probably one more 2fa using code from mobile number.
6. A lot of country can play on 1xbit not quite sure if they use a geo-blocking.
7. The minimum bet is 0.0005 BTC I'm not sure but for small players this is a little expensive I think the acceptable is 0.0001 if you can make some changes with this, that would be great.
8. The minimum withdrawal is 0.005 BTC that's really high in my opinion I haven't check the other currencies for their minimum withdrawal
9. There's no on-site exchange.
10. Mobile app is available that's nice.
