Infinite bankroll 
With martingale on 2x odd, doubling your bet everytime you loss you will loss all after some red streak in series. 

I have tried this myself on bustabit and lost over 0.10BTC  overnight. 

Someone just put another 100BTC into yolodice? 

I have lost all my balance in yolo trying to get listed in low number roller 
Quite surprised to see few players who have managed to secure more than 1 position in top 10 list for bonus. 

I have sent pm, waiting for your instructions.

I too lost around 20$  
It is too addictive and can't stop myself from playing.

Also hit 10x few times but ultimately lost all at end.

I have deposited in bubblecoin several times and there was no any issue with my deposits, hope you will get your problem solved.

Have you tried bet365.com they accept both skrill and neteller and trusted by many.

I am also trying my best to secure a position in top 10 but i started to doubt that i may not roll lowest number even after losing more than prize money. 

However this is very interesting competition.

Freebitco.in may earn far more than 4% annually with their users bitcoin so this is actually a good business strategy they have started. 

I think only death is guaranteed in life, taxes and freebitco.in interest are only optional. There can be tax free country and freebitco.in may discontinue this annual interest if they fail to secure 4% annually with their investment. 

Site has no any SSL certificates so its better not to enter any of your personal details like passwords and credit card details there.

Also the link OP have shared looks like a referral link rather than a normal site link so may be he is trying to get free referrals. 

All regulated casino must have KYC policy to remain in business and that can be big problem for lots of users from countries where gambling is restricted.

On the other hand casino that are not registered anywhere and only accept bitcoin don't ask any personal documents and protect personal privacy but they can shut down and run away without getting caught.

So if you want to protect your privacy than you have to take risk of getting scammed but if you like to remain in safe hands than it will cost your personal privacy.

It looks like he is giving free VIP pick every week if you join nitrogensports under him https://bitcointalk.org/index.php?topic=881042.msg18436882#msg18436882

Also his picks looks promising because he is constantly updating his thread for last 2 year with his picks, so looks legit. You can try him but you have to be careful about bet size and odds.  

I have one good suggestion on possible tournament. I think you will get good results from referral competition with good leaderboard prizes or increase in referral commission for top referrers.

Implementing shapeshift api can be enough on starting to accept deposits in altcoins but i don't think it will be quite reliable to have withdrawals through their api due to high bitcoin transaction fee in middle as well as their price spread. Users may loss so much due to those fees.

I think it is 50x which is quite high and only slot will contribute 100% towards wagering requirement.

They have started their dice with lots of advertising campaign here in the forum and also doing well but we will never know why they decided to close their site. I have also played there for several times but luckily i haven't left any bitcoin there when they go down.

I think they will never come back.

May be it will require few more days/weeks or even months for them to open withdrawals for users who have completed their verification procedure. After verification they may also ask for source of those bitcoin before allowing users to make a withdrawal.

You are wrong brother, it has never been effective model to distribute products. The one who will get all profit are the one who is sitting on top of the MLM pyramid.

We can't say this, they are selling their premined coins to newbies who even don't know what is crypto with the help of few people who are willing to scam newbies for few $ in profit.

No i haven't invested in any MLM crypto and i don't think i will ever invest in them.

For me its bitcoin core, bitcoin unlimited is just another bitcoin clone that is trying to build support and add inflation on bitcoin with their wallet full of bugs and incompetent devs behind the project.

We don't need two bitcoin.

Yes it can be tracked but when you have bitcoin and send them back and forth using hardware wallet or light weight wallet like electrum it will be hard for authority to track your bitcoin transactions.

For additional privacy use well known bitcoin mixing services like bitmixer.

There are few more reason why i consider their investment opportunity quite risky:
1. They haven't provided enough information on how they are protecting their user's bitcoin which are in their wallet.

2. They are offering fix 4% yearly profit which they may or may not make in longer run.

3. You can't use their wallet as web wallet, it doesn't seem to have enough security measures and you will not have full control over your bitcoin.

However regarding trust, we can trust them because they are paying for many years.

Sadly i have created account with very weak password and someone have drained my bonus. 
Anyway its my fault, now i have changed my password.

Another suggestion for you:
- Add email verification on withdrawal.

Thanks for that bonus, which is now being enjoyed my some hacker.
