Now, the new question is.. How are the host of this site being "paid" to cover his/her cost to host this site? Do the casinos pay the host and if they do.... How biased are the host towards their reviews?

OP can you answer this?

Welcome to forum, there're some stuff need to be reviewed.

I don't think this is accurate, we already saw some casinos freeze/hold funds due to suspicious activity or withdraw huge sum money. When they detects suspicious act, almost all casinos will ask you KYC or even when you registered they ask your KYC.

Also you need to change the url from coinbase.com to wallet.coinbase.com since you're discussing a wallet which have private keys not an exchanges.

So... where are the reviews?
Clicking on the "read review" button takes me to the site with an obvious referral code in the address bar. I tried it with FortuneJack and mBit with the same result. Even if I click on the "Review" button at the top and select those two casinos from the dropdown menu, I am getting redirected to them instead.

I think you have started off badly and it's your own fault.
And regarding the selected casinos to "review". From the five of those that are getting advertised on your site, 3 have negative tags here: CryptoThrills, BitStarz, and mBit have all received negative tags by the community.
If you wish your site to become a trustworthy and independent review platform, this is not the way to do it.   

Basic question: Do you charge for reviewing?

I'd love to see your honest review of 1xbit casino and bookmaker.

Are you anyhow linked with Bitcoin_Arena profile on bitcointalk- https://bitcointalk.org/index.php?action=profile;u=1269497
When I saw the username, I thought it was the same guy and I was surprised to see a newbie OP. Anyway, I would be pleased to his involvement in the site as he is quite old guy here. Please clear this issue.

There are many casino review websites available in the market today. So you have entered into a very competitive market which may make your journey harder than anticipated.

But at this stage, we are missing an aggregator which will collect every piece of reviews and feedbacks into one place and the visitors will get a bird's eye view on a casino's performance.

Think about it!
