I just made a glance through your website and it looks quite much simple and lacks the basic necessary details which a directory or a Gambling casino summary ought to have got, rather than been plain just the wasy you displayed in your website. Because I would have suggest why not you draft each of the crypto gambling sites you listed on your website with for example the "Name", its type (i.e if is a Sport booker or Casino), the minimum deposit & withdrawal, the year it was launched and lastly the major cryptocurrencies been used on each of those gambling sites.

Example;

Name: Stake.com
Type: Both Sport booker & Casino
Minimum Deposit: $5 & above
Minimum Withdrawal: $20 & above
Year launched: Since 2001
Major Crypto been used: BTC, USDT, Tron, XRP

Note: This is just a rough example.
