It depends upon the total bankroll casino already have from other investors. If bankroll is not that big even small amount may make sense and profit will depend upon numbers of players on the casino. But if bankroll is already over 100 btc than 0.01BTC may not give any significant return like 10% profit on 0.01BTC will be only 1$ while the one who may have invested 1BTC will earn 100$.

Site is not accessible on my side, is this related to server problem or you guys are doing some maintenance.

Yes this site is rigged and not provably fair, just leave this site don't play there again.
Many other have already proved that even with 98% chance you will get red streak in row. Also haven't seen anybody successfully making withdraws from them.

I don't have idea about trezor but blockchain.info provide feasibility to choose fee and they also estimate time to wait for given fee. This will only turn out to be exact when there is not much congestion on bitcoin network but if mempool is full better to just slightly increase recommended fee by them for confirmation within 1 block. I am doing this from starting and even right now mempool is almost full but got my transaction confirmed within next block using around 150 satoshi/byte fee. 

If he is just playing with free tickets or for fun than i will say it as entertainment rather than gambling. And he is not even risking anything from his pocket, so i will call him addicted to game not to gambling. But when he will start to play with real money from his pocket in the same rate like you have explained, he may develop addiction towards gambling.

I used to bet with cloudbet but i haven't used them for long time and don't know they are paying out these days or not. 500 bitcoin on single withdraw request  i am quite sure any of the sportsbook will go through detail investigation on that one.

Torwallet.com --- better not to use them.

Can't see fortunejack and many other casino in the list which are provably fair and trusted. I have played in pocketdice.io, fortunejack, crypto-games.net etc which have probably fair games. You can review them in your listing also don't forget to look for better template for your site.

Bankroll is quite low so better to open investment offer for others but before that just make sure there is no any security flaw/bug and also you need to work on your design/UI.

There is one flaw on displaying bets history

How 18161 bet id is played on 5th feb while lower bet id than that was played on 6th feb. This doesn't make any sense 

They have 5% house edge which is very high compared to what other dice site have i.e. 1%
House edge is great factor that can affect your winning, better to not play in freebitco.in

Fortunejack, primedice, bitsler etc are pretty trusted dice sites.

Have you clicked i deposited button just after you have sent bitcoin to deposit address? To get your deposit you don't have to wait till it get confirmed, your deposit need to get confirmed only before you can request payout after winning.

Also have you saved the URL from them because as there is no login system you have to save the url to access same account again.

Best one for me is fortunejack, primedice, directbet and i think i have lost most of money playing dice on primedice on early days. Also placed many sports bet on directbet, fortunejack is new one to me but i have already started loving playing on it.

There is no any real service/tipster who can predict match accurately and if they can predict match accurately why they will sell their tips rather than making whatever they can with their own money. Doing own research about the game you are betting on is better than following other's tips.

You can't make good profit out of moneypot based simple dice site. Most of the profit will go towards moneypot investors and there are lots of dice site already on the market, so you may struggle to attract players on early days. Good marketing campaign like signature campaign, contest, twitter & facebook campaign etc may help to gain some players.

It will be just a foolish decision to bet on games you don't have any idea of. I mostly bet on soccer matches and only in the matches where one of my favorite team is playing or atleast i know the performance stats of the teams playing. It will be pure gambling to bet on sports which you don't know.

They will not pay you because i highly doubt they even don't have that 0.3BTC to pay you, better to stay away from this site. Owner seems to be here just to scam few bitcoin and run away. 

You have no budget and you are looking to buy gambling site  
You have to code full script yourself if you don't have money to buy it. 

Theme looks clear but does this theme is optimized for mobile too?
Rather than listing all sites in one long page why just don't add only titles on homepage and whenever someone click on each category page will expand either in pop up or just under the title without need of reloading whole page.

There are few bootstraps templates which have this feature but i think you have to buy it.

There are few places where i place sports bet specially soccer matches (if my favorite teams are playing). One of my favorite is directbet but sportsbet, nitrogensports are also good sportsbook you can check them.

For betting on esports, nitrogensports is good but better to do your own research on matches rather than following suggestions/tips by other people/site.

You can send email to their support or just pm https://bitcointalk.org/index.php?action=profile;u=917361 (DuckDice.io)

Their commission is one of the high among other dice sites. It will be nice to see few more games along with dice in their site in future.

Very cheap attempt to scam people 
Nobody gonna send you any penny dude, if you can double bitcoin within short period of time than why you are asking for bitcoin from others. This doesn't make any sense, totally bullshit SCAM
