If you are playing within their rules and are not withdrawing huge amounts you would not face any problems.The problem arises in certain cases like suppose a user had multiple accounts problem and casino has mentioned this as violation or any other issues they will take action against player but if you are normally playing it won't affect you much.

First of all he has done lot of mistakes with his bitcoin investment in the start also as you have mentioned:

1) He invested without any knowledge which is against the rule of trading as if you are not having knowledge or information about what you are investing in you should not do so.He should not jump into this before making some quick research

2) His greed for doubling his money as this is not make you rich scheme overnight and this is among common misconceptions arising out of your greed and ask you to invest money.You should look at charts and hold for long term if you want returns not double your money

3) When there is such thing why your friend or any other victim don't care to find why Tesla or Elon would give you double what you give them? Is this some charity or donation going through or they have abundant funds to distribute to each user?

4) You should have directed him to some useful resources on the forum only instead of guiding him to those crap YouTube channels which are not giving any informative thing rather then some knowledgeable things about crypto so avoid them.

These are lessons which will help him to stay safe in the future if he considered this loss as lesson.

Even if you are sorry it won't help you at last because ignorance of the law is not a plea in real world also so same goes here also.As you said better be safe at first only so reading the terms is much better because if the casino is trying to make you fool you also have the idea about what was mentioned in their terms.

With every wager the casino will make benefit from you even if you win and for each loss they have the full amount.But you will see lot of gamblers including us look for the various deposit bonus when we sign up on any casino and what are their promotional strategies so it's beneficial for them to get incentives.

This is what they want at the end to make players engaged in gambling so they keep wagering on their platform.These bonus give users more interest in particular casino and they are happy.Sometimes we see that codes are sent to inactive players so they get attracted to gambling again and when they start playing they wager more becoming active players so it's all under marketing techniques which is good on both ends.

Tweets is something else where you mention everything in points and users are reading them and even if you ignore them it won't affect you much but these terms ignorance can cost you if you overlook important conditions.But a normal look at them spending few minutes would be better for us a gambler.

So you think you can just earn by mining without doing anything at all? The humanity which believes in doing nothing and getting paid for it have nothing in their hand as you can't get anything for free here.The mining you are talking about needs ASIC investment and then electricity cost and much more but still there's no guarantee you will earn rewards for it and they are working for it.So you need to understand these things before making such statements and comparing it with bitcoin which has lot to do and solve financial problems.

For most of the time you won't have any inconvenience playing on casino but the actual problem will come in rare cases where you accidentally or intentionally violated the rules which gives more scrutiny to your account and withdrawal are stuck but otherwise playing normal and KYC procedure you will not get any problem.

They are some sort of profits to the casino in the end because they are getting more bets from you by providing these bonuses.They have marketing expense but also gain a lot from it in the end and for players also if they get some good wins out of it they are happy for it.

It's not that bad news come in bear market but in reality the bad news are the reason why we see price dips and opposite is when there are all positive aspects we see lot of investments both retail and institutions leading to bull run phase which is we need to understand.The more big pumps come when there is more good news at that time like some big company accepting it or regulations for it but if we say there is timing for it then it's not correct.

The thing is even if we keep our savings in banks they are becoming target of inflation and reducing the fiat value with time so your $100 in banks would not be of the same value after 5 years also so the investment in coins like Bitcoin is what safeguard us from high inflation.No doubt there is risk you loose funds with some dips but it doesn't mean it will not grow afterwards so taking small risks are what will give you return in future.You can have partial investment and rest savings in bank which protects you in both cases.

See if you are interested in altcoins only then short term hyped one's are best choice because at least you have chance to earn profits over them but keeping in mind they have long term potential it will not benefit you as records says most of altcoins have turned into shitcoins over long term so you will loose money.But there are some in temporary hype like Shiba,RenQ finance or what else you have in mind but for me altcoin investment is not good rest your wish man.

For me personally I don't prefer Martingale strategy at all because you are at risk of losing more with it but don't know how some players find it good because they want to win no matter how much they wager.I am also of the opinion that you place small bets and even if you have decent win not too big that's really good for you giving you joy instead of losing more in high hopes.

If we see that btc has been here for more then a decade and countries are now making regulations about it and banks offering crypto related services whereas in the past they were completely against it so do we still call it hurry? They have come up with this move which is good for the people but all those who buys with banks also remain under their radar so a kind of control over them also.They are seeing crypto as  a rising market of which they want to take benefits of so they have planned this move in conflict and with China.

This is how gambling addiction can take serious turns because you can't control yourself from gambling while you don't have financial support with you to keep up the bankroll but this is something rare and criminal mind where you are putting a step ahead and kidnapping your own granddaughter.

Kidnapping is criminal offence no matter what's the purpose behind it because at last you are demanding money from the family even for gambling so we can't say it's gambling is good in these cases.When you become too addicted your senses don't work and you follow the wrong paths which is why stop limit is necessary.

They have to make strategies according to their marketing and promotional budget so they cut sometimes these bonus and reduce giveaways also which is the case with most of casinos.But the thing is when you are competing in this market you can't satisfy all the players as they have different demands and casino can't operate on all of them but makes wise moves according to whole demand and their plans.There are many such reviews of which they cannot do anything.

No hacker can have access to your telegram or any other account unless you made some mistake on your part.There are many scammers on telegram because of all the groups and you clicking on some phising links which injects malware in your system.This is why it's easy target for hackers but you can have more security with 2FA and not joining these groups preventing these scams on your part.

I would say if you are lazy but still you can check for main conditions like deposit options, withdrawal amounts like minimum with KYC or without,live support as they are some important stuff on which the issues arises later on.So you must be careful in them along with other also but if you are playing without any cheating you won't have to face any issues at all.

That much amount can be wagered by small gamblers also over few months period with small bets also.The duelbits have made this system after analysing the market conditions and also provide rakeback as you said which provides more benefits to players while wagering and reaching VIP first level and avail those extra bonuses.

Your friend also need to know that bitcoin transactions cannot be traced when we use mixing services otherwise you can have the record of each transaction on the blockchain and it's not completely anonymous.Secondly about revealing the identity of Satoshi then it's not possible because so many years have passed and we all have developed so many theories about it along with many faketoshis coming up but nothing has happened with bitcoin so why are you concerned now? The situation is same and governments won't be able to stop it rather regulate it to take more benefits out from btc.
