Yes you can change it whenever you want to withdraw. In bitcoin address field you may see the same bitcoin address you have used before but you can easily replace it by pasting new bitcoin address.

Only public is in favour of bitcoin ETF but not the SEC (Securities and Exchange Commission ) and they are the one who have to give approval. So i don't think bitcoin ETF will be approved today (March 10) by them. I am thinking about buying more bitcoin if there will be some price correction after this.

I have also seen sportsbet.io asking for personal documents in the name of investigation. Don't know why bitcoin casino have KYC policy at all. If they are registered somewhere than they may have it to comply with rules of the country where they are registered but for other there is no point on asking for personal documents.

Ok here is my review.
I got 500 satoshi to try and played for around 10 rounds with 100 satoshi bet size but lost all at end.
Playing was smooth, there was no graphical lag on delivery of cards. Couldn't try withdrawing out because i lost all, but in future i may continue playing with some deposits.

I personally trade bitcoin for USDT in poloniex and it is best way to remain in safe side during huge price movement like right now. I have already sold few bitcoin when price was around 1300$ and now waiting for price to get some stable price after this correction to buy back. However its better not to keep all your bitcoin in any exchange platform but we don't have other choice.

How viaBTC accelerator works:
- You submit your transaction ID and they have limit of 100 transactions per hour which reset every hour.
- Viabtc have huge mining farm so they will mine few blocks every day or even every hour, they will prioritize the transactions that are submitted so fee those transaction have doesn't matter.
- When viabtc will mine block your transaction will get approved.

But i don't like them personally because they are trying to promote bitcoin unlimited which may lead to split of bitcoin network.

There is no way to predict the exact price movement for bitcoin, you have to keep an eye constantly on different bitcoin related events and news to get idea about the price movement. There are lots of things that can affect the price so nobody can precisely predict the price of bitcoin.

Read this one, hope it will help you to understand how it works https://thebitcoinstrip.com/blog/what-does-provably-fair-mean.html
There is also good discussion on concept of probably fair here in this thread https://bitcointalk.org/index.php?topic=1431468.0

Site is down for me
I think this is hosting related problem.

EDIT: I have refreshed page for 3-4 times and finally accessed site. But it is quite irritating to encounter 2 pop ads simultaneously.

But i expect this downtrend to continue because there is no doubt that bitcoin ETF will not get approved by SEC on current situation. Price may see some more correction after tomorrow than within next few weeks price may regain $1300+ price.

Almost all of the bitcoin debit card providers are retailers of wave crest holdings so they have same monthly fee of 1$ and have unfair exchange rate. You will never get market rate in any of those card provider. Also wave crest have changed their policy about unverified cards, so to use their cards with paypal, ebay etc you have to be verified first.

What is the price for your VPS hosting http://www.curacaowebhosting.com/products-services/vps-hosting-curacao/
Price is not given in the site and does price depends upon the speed of the port.

I have also heard Bitbox script is full of bugs and already few sites using them have shut down, OP you should also close your site and this script doesn't have anything new so i don't think anybody will be interested to play in your platform.

I would like to try your game but as jacee has stated captcha on faucet is not working for me too. If you can add few satoshi for me to try than my username is: piloder there.

How you can claim directbet as clone of betfair nothing looks similar in them. Directbet is not providing badminton game may be because there is not much margin for sportsbook in that event or their are some other technical problems in adding it.

I am using google chrome and there is no any problem with loading, you can upgrade your firefox to latest version or start using chrome.

Android app will be cool feature but google play store will never allow gambling related app. Duckdice team can simply release .apk file which can be installed in any android devices.

How you guys have pocketdice within your site 

Also there is many things you have to improve including different header for logged and guest users. There is no need to show balance area, deposit, withdraw buttons in guest mood.

Casino that accept investment from users will show full stats about how much they are making each day/week/month for transparency and the amount depends upon several things. But there is no way to find out how much other gambling sites are making because they like to make their stats private.
