Gambling is not the only one industry that is using bitcoin, i think majority of bitcoin is being used in darknet marketplaces however gambling is also one of the biggest bitcoin industry.

Without gambling also there will be bitcoin 

Investigation for what? Are you guys still in beta stage so looking for bug in your system  
Also 0.3BTC shouldn't be bigger amount for you because you are claiming 50,000 BTC in bankroll.

We will wait till he will get paid in full.

Good idea could be making blockchain based game connected with moneypot. But you can't earn good profit with moneypot, try to make secure platform first, allow investors to invest in bankroll and share your profit with them.

Good user interface is must and you should also have night mode layout.

I have also deposited there and played for few round and same happen to me too, basically it is hard to understand how those viruses are created that just split blob into many small blobs as well as even small blob can take away some credit out of bigger blob. I also tried depositing 0.005BTC and was the biggest blob in the game and also in the leaderboard but it keep decreasing and hit by virus which split my blob and all my money was gone. 

I have also heard about them before but i will suggest not to store any amount of bitcoin in that address generated by them. You can use it as show off address and send out whatever you will receive on that address to another address as soon as possible, this is risky so if you want you can use it at your own risk.

Found that it is reversible, you can find about it in their terms of service here https://www.goldmoney.com/terms-of-service

What problem you are talking about? Those spam transactions clogging bitcoin network? If yes than those attacks can't last for long time so that will not cause much trouble if you add few more satoshi in fees.

Price growth is healthy this days and i think price can easily cross $2K by end of this year.

Blockchain tech is just booming and there are not much developer/experts so if you can learn about it quickly than you may still find your place as one of the successful blockchain expert in the world. You may get hired by some big corporate giants or you can start your own blockchain based projects. Good luck..

Looks like you are trying to steal bitcoin from others, you are trying to lure others to invest in your ponzi plan  

Bitcoin price will be stable in future when marketcap will grow to trillions dollar and block reward get almost zero per block. Any assets that are in trading platform are subject to price swing so it is normal to see price volatility for bitcoin.

You can check my signature, they are quite reliable and also trusted by community. They offer a lot of games with live dealer including roulette. Hope you will win some, good luck 

Definitely luckyjack in fortunejack is quite good daily giveaway but i haven't seen any other platform giving away such a huge amount daily in giveaway. I have recently came across betcoin.ag which have some daily bonus like offer, but most of the time they just give +1 status point which can't be converted into cash. Also they have some open scam accusations and so hard to trust them.  

-> I think if you can run gambling platform smoothly and can insure security of bankroll than it will be profitable for sure.

-> Yes, new and pretty addictive game will always be in demand. Look at bustabit, satoshimines, luckyb.it etc they are successful because they have delivered games with pretty new concept and addictive.

-> Market for bitcoin only casino is still not saturated but if you are only planning to have dice, slots etc than market for dice site is saturated to some level.

There is list of bitcoin related scam sites and it also include few casinos but number of scam gambling platform is comparatively low or hard to find all of them.

100BTC+ in single bet 
I will suggest never bet like that and i don't think any casino allow that big amount in single bet. With 1.2x odd you can bankrupt any casino if you turn lucky, so most of the gambling platform have very low max win/bet amount limitation.

I will rather prefer to play in satoshimines, if i remember correctly this was on sale few weeks ago. Looks like OP is new owner. Mines = Donuts 

I think it is almost same in other platforms, but i personally like that 10% cashback and free spins offers. May try it but 0.05BTC minimum deposit to get free spin 

I love to bet on live matches specially soccer matches because we can get really nice odd during match after one team score or game is running on tie for longer time. 

Bitsler is trusted platform and running without any issue, and like in most of other casino some delay in getting your withdraw is common because whenever system find something suspicious it will just halt instant withdraw and wait till it get checked manually by staff. Even though your withdrawal amount looks small, some delay is normal.

I also think he/they are quite busy with fixing other bugs but 1 week+ is quite long time without response. I have played there before so i am having closer look in this issue. Hope this will be fixed, i don't like to see coinroll getting shutdown after being trusted for so many years. 

Few of the important things are ;

Community Trust?   
House Edge?   
Provably Fair?   
Proof of Funds?   
Security (has 2FA?

Graphical interface and contest/bonus are just extra feature and may not play important role like the things mentioned above.
