Exactly... That is the problem. A wealthy participant or whale could somehow guess the right amount if he/she keeps betting to the level that it becomes difficult for small bettors to participate. The model is prone to abuse If Op has no countermeasures

Self control or not getting attached to "cute things" in casinos... This is self-help method. The second method should be from gambling owners, they should remove things that get people attached to their casinos, especially the bad thing that ads no value to the live of their customers. In my opinion, people should be able to bet on things as long as they're non-harmful things, and done in moderation. *Safe betting* should be encouraged more by casinos.

PoS(from what I know) isn't really a good solution either. Too much power is given to people with large stake. I think this is technically centralization, because you centralize important decisions making with no checks and balances, and no quick remedies to potential violations.. Another potential problem with the staking model is that it will encourage wealthy people within a decentralized networks to have to much influence on things. This can be used by bad actors against the network... So, there should be ways to check any potential abuse from this. I believe reliance on principles will be one of the most important ways to help checkmate them.  Besides, if you are depending on principles, you probably will not allow that kind of Power concentration from staking model.

In regards to number 3, some kind of Proof of Work that is environmentally friendly can reduce/prevent the problem. Should probably be the most efficient pow available that does very important work. Decentralized networks need to avoid things that are energy(even good energy) demanding when there are better alternatives that do very useful jobs efficiently without sacrificing any Bitcoin/decentralization principles.  If a decentralized community focuses mostly on doing useful and good things, our energy usage will be justified, as long as it is good energy.

Ofcourse! But you have to make sure such partners agree with your terms, and your terms need to be public/real blockchain-friendly. This will help you guys stay on course and help you solve difficult problems in public Blockchain-friendly manner. Remember, one of the most important reasons for choosing real decentralization over centralization is to avoid problems that are inevitable in centralized conditions

This is very important to carry everyone in decentralized world along. If you don't know how to explain your ideas or difficult subjects to a 5yr old child then find someone who is excellent at making difficult idea simple to help explain them. I guess the good & technically gifted minds are probably busy to make difficult words simple for the majority?  
So, I believe strongly that better understanding will help the communities alot. The communities (who should be armed with decentralized rules and principles) will be able to know whether you are moving in the right direction or not.
In my opinion, an "enemy" can easily takeover a community by consistently using terms/word that are hard to understand by the majority. This is another source of risk to decentralized/crypto communities that should be taken seriously

I guess the arbitraging is used mainly to keep the price of the stablecoin thesame across exchanges. The arbitraging feature is probably included just incase the stablecoin price becomes too different across exchanges?  I guess they use different algorithm to maintain the stablecoin at $1. If for example USD increases/decreases in price, the algorithm tracks & changes accordingly while arbitraging only helps keep the stablecoin at almost thesame price across exchanges. The whole activity of a stablecoin should be very transparent and decentralized otherwise not worth trusting too much.

You missed backing this claims up with good proofs. I think the safer, more decentralized,  and useful one among them is probably the what I would pick if given the option to choose any of those.
So how do we determine which one of them fits  my criteria. We probably need to refer to the important ideals of Bitcoin/crypto to determine which coin is closer to the ideals. If crypto stuff are rated this way, you won't "derail" too much when looking for safe & useful projects.

Interesting (if true).
I wonder if the exchange will allow only custodial usage. Would be nice if they include the use of non-custodial approach for players. And they probably shouldn't have too many difficult terms and conditions to attract lots of participants.

Societies should probably stop making nonbeneficial things attractive. We need to stop gambling with people's health for example.  Bad sugar, alcohol, food etc shouldn't be put in attractive packaging nor made tasty/sweet. The healthy things should probably be made more attractive. Things that aren't bad nor very beneficial should be used more moderately. Moderate usage really depends on how much of doing or eating something can cause you problems.

What happens if no one wins in the end? Do you redistribute the money back to the owners?
This sounds a little bit like auctioning, only that the participants (aside the winner) loses everything.  I wonder how much goes to the lottery owner.

Interesting. But why not have more bettors win something too? I guess there should be First to Tenth prices for 10 winners or even more. The top winner wins the biggest while the last wins smallest. This could increase participation, you know.

Hope the lottery owner won't know the amount in the pot, and other important data?
This will probably work well in decentralized manner

Well, it's about people who need help and are probably not getting it. Geographical location doesn't matter in this case. Ofcourse I know the country is doing very well, according to this world standard.
By the way, If donation is not necessary, I wonder why some are requesting for it on  this community. I guess they just feel the need to help.  I don't really know much about what is going on in the Country aside from bumping into news concerning the virus mostly on this forum and some social media/forum.
Everyone needs repentance, forgiveness, obedience to GOD and possibly "prayers of the saints" in his/her society. If the saints pray against your oppressions, GOD always answer them. So be very careful how you treat them, else they get agitated and call upon their CREATOR.

I think it's a project based on dentity management. I don't know if it has changed though to include other identity enhancing things like reputation, security, better decentralization, privacy etc.
I think a Crypto-based identity project that does not adhere to the important ideals of decentralization, is not worth using in a decentralized community.  No single person should have access to your personal/unique identities IMO. It's also a bad idea to have them stored centrally.
As regards the bitconnect coin, thought it doesn't exist anymore?

Morning is probably my favorite time too. I  post any other day as well especially when I am in a sound mood. I try to avoid posting when my head is "foggy". And bad foods normally give my that foggy feeling. I also sometimes read posts while walking, then post later when I find somewhere to stand or sit.

You could actually combine good crypto trading  tutorials on youtube (and possibly good ebook) with Demo trading. Demo trading can be helpful in the area of practice. And you can learn in this way for free, rather than paying a "professional advisor".   Try Googling: "best crypto demo trading sites" You'll probably find something worthwhile and safe to use

Depends on how sustainable the global peace will be in the world and its current order. Global peace is unlikely in a world that doesn't really know its real CREATOR nor submit to HIS true rules & teachings. I think there should be boundaries in a lawless and confused world else "bad things" will spread quickly and we end up destroying the world/ourselves.

Question is a bit funny. I really doubt fiat currencies (as they currently are) will ever beat Gold. Real cryptocurrencies could beat gold in the future when probably they become more useful, valuable, durable, long-lasting,  deflationary, secure etc. Crypto needs to be backed by special kind of assets to become more useful or valuable.     Fiats would need to become more like real crypto to stand a chance.

Interesting point. I guess peer-to-peer betting can just take place randomly or occasionally in regular casinos. Your point is likely one of the reasons there are few p2p betting. I guess many people are mindful of very skilled players. Watching people play before  deciding to play with them is probably how others determine whether they can win a p2p challenge

Guess there are different between "gambling addiction" and "problem gambling". Problem gambling could also include people who gambled excessively in their first time they ever gamble. Such people will likely not gamble for a long time if they are not pleased with their losses but some could still come back to gamble despite their losses, either to "have fun" or try their luck again. I think the fun seeking gamblers could end up getting addicted if the gambling is more fun to them than any other activity outside gambling.
I guess the words (problem gambling) concern all problems associated with gambling, which includes addiction. Casinos should probably be made less addictive, people should be taught  to gamble safely before they gamble, people that are vulnerable to addiction (especially children)  should not be allowed to gamble. It's also important to "solve the real cause of addiction"... like depression, sadness, etc

Number two is quite interesting. Guess you are trying to suggest that gambling addict got their habits from gangsters or mafia. Well, that probably depends on the kind of gambling. And gangsters videos are probably where they mostly learn the habit from. I don't think this is totally the case though. I tend to believe that people who gamble regularly without being profitable are gambling addicts.  "Enjoying" gambling (without being profitable) can lead to addiction or can be considered an addiction. .
