i feel like a couple of things are being confused with each other here.

having a coin listed on a centralized exchange is not going to change anything about that project. after all bitcoin is THE decentralized cryptocurrency and it is listed on all centralized  exchanges and decentralized ones alike.
similarly having a coin listed on on decentralized exchanges doesn't change anything about that project.

what is important is the project itself. there are many that are only pretending at being decentralized, specially tokens, when they are really not. having their token listed on a DEX is not by choice but by lack of it. their token is usually either too useless or too unpopular to be worth listing on a centralized exchanges since they are always bigger and more strict about what they list.

as for fake volume, it is being blown out of proportion. existence of it in a market is not the end of the world. manipulation exists everywhere in the world even in traditional markets.

so again it comes down to the project itself. if a cryptocurrency is really useful then it shouldn't care about where it is listed or whether its market has some manipulation, fake volume,... the utility ensures its success and survival.

almost all cryptocurrency oriented casinos have no kind of license and are not working under any regulations or anything like that. additionally they do not work with fiat every. that means if any of this type of casino is asking for your identification they are trying to scam you because there is no reason for it.
exchanges on the other hand are either working with fiat, want to add fiat in near future or are under a lot of pressure from government and are under a lot of regulatory laws. so it makes a lot of sense for them to ask for your documents.

instead of wasting your time on things that don't matter at all you should instead spend some time looking behind the curtains and figure out how they are scamming you with a front that looks like a "business".

the whole point of creating decentralized systems is that people no longer have to "give their trust" to anybody or any team. instead they replace it by either their own judgement (which i achieved when they run full nodes and vote for any change like any democracy in its true meaning) or place it in the judgement of the majority of the network which should consist of enough number of independent individuals to eliminate the chances of one group taking over.

otherwise if you want to put your trust in 1 person then why even bother with a cryptocurrency when enough centralized companies exist?

there was a pump and dump recently and people were panic selling which made the ethereum network severely congested and it has increased the fees by a lot that is why people are complaining about their stuck transactions for days (you are not alone). unfortunately there is no alternative easy way defined in ethereum network for users to mitigate the situation either. all you can do is wait and hope to get lucky and for your transaction to go through some day.

of course it is because there is nobody else to make any decisions and there is not much of a network to analyze those decisions as a proposal and decide whether they  wanted to accept them or not. that is what happens when the projects become centralized, only one person or one team makes all the decisions just like banking system!

bitcoin cash is an altcoin while bitcoin core is a full node client. what you said makes no sense because it is like saying i like eating apples instead of the color blue

if you want to be successful you should learn to make your own analysis and decide how to invest instead of asking others.
my strategy is to never "invest" in any altcoin for long term because i have no faith in future of any of them. and so far we have seen i am right.

these are centralized altcoins that are shady and mutable. i won't go near these apart from day trading and only during their pumps.

these 3 may be better, but again i don't like the long term outcome of any altcoin. LTC is a copy of bitcoin and ZCash is doing a poorer version of what Monero does.

this has never happened ever.
so far that i have seen from the market altcoins have always only gotten pumped whenever bitcoin price became stable. after the 2016 halving bitcoin price became stable for a moderately long time which means we saw an increased number of altcoin pumps until bitcoin started to rise back up again which made all those altcoins dump hard.
i wouldn't call this "surpassed bitcoin" in any way. specially since altcoin pumps can never last and never will.

it is a well known fact that altcoins have always gotten dumped whenever bitcoin price moves both up and down. it is mainly because all traders are trying to increase the amount of bitcoin they have to maximize their profit and that means dumping altcoins and going back to bitcoin. of course altcoins being mainly pump and dumps doesn't make things any easier for altcoin traders.
the loss of money is partly because of this and partly because most traders are either unfamiliar with the altcoin market or don't want to accept how it really works.

one big problem with businesses that ask for KYC from only a part of their customers is that at any moment they can change their rules and ask KYC from all of their customers. most of the times it is not their own fault either but the authorities are going to force them to ask for KYC since they already have one foot in the door.

it was all a plan to pump steem these days and Justin Sun knows it very well which is why he bought the coin from its previous owners. nothing is changing with the coin though it used to be centralized with other owners and now it is still centralized with a new owner while these owners are making millions from the pump and dump that happens during the transition

Corona virus affected US the most with their 5000 new cases per day and that has caused a lot of country wide panic that has crashed a lot of their markets. with that panic many bitcoin holders feared a drop like that so they started panic selling.
we all know that whenever bitcoin drops, altcoins dump 10 times harder which is why you see cryptocurrencies dropping this much. however COVID-19 has nothing to do with bitcoin which is why bitcoin price went back up.
and again we all know that whenever bitcoin price rises altcoins get dumped again which is another reason for altcoin drops.

no bank has never been interested in using XRP all these years and it is not going to change with a random bank in Bangladesh either.

there is nothing illegal about using the technology though. for example producing and selling crystal meth (XRP) is illegal but the technology that is chemistry (Ripple) is not illegal and can be used elsewhere for other purposes.

banks are interested in and use Ripple not XRP. Ripple is the technology and XRP is the token. it is like saying Facebook is using bitcoin just because they used blockchain technology to create their own coin. we also have seen in the past that  some of these banks discarded their relationship with Ripple company as soon as they learned the technology and could use it on their own.

being centralized means even the cap of 100 billion is meaningless let alone simple things such as "locked coins". they can do anything they want just like they have access to all the coins that are in existence not just the ones they hold. just like how they stole the coins from one of their team members after they kicked him out even though he was the only one with the private keys!

that is pure nonsense.
there is no way anybody could know who a bitcoin address belongs to and where the money is going. the fact is, there are lots of big businesses some of which are exchanges that perform large transactions like this. you can't call them "whales" just because of that. for instance gambling sites own a lot of bitcoins, payment processors, mixers, popular merchants,... are other examples.

it can only happen in your dreams but never in reality. here is why:
1. XRP is a shitcoin and everyone in cryptocurrency world already knows this.
2. XRP is useless so there is absolutely no real demand for it apart from pump and dumps.
3. it has one of the biggest supplies among altcoins. such enormous supplies automatically prevents price from going past certain levels.
4. XRP is centralized which is yet another reason why nobody cares about it past its pump
5. due to pump and dumps everyone knows the "dump" is coming so naturally they always dump it before it goes any higher than a couple of bucks tops.
6. the company that owns it also wants to make money. so each time they pump it, them dump it themselves to take the money out.

POS and airdrop are in direct contradiction with high RIO.
basically when you give away a lot of money to a lot of people for doing nothing (that would be the POS payments and free airdrops) you are increasing the circulating supply and the dumping pressure on the market and there is no way for such coins to go other than dropping hard down and crashing in the long run. all of the altcoins that have done this so far had the hardest crashes.

your mistake is that you think something like steem has any "supporters". the fact is that nobody would have ever cared about it if there hasn't been a spamming platform for people to earn small amounts of dust. in other words those whom you call "supporters" are mostly the spammers who are trying to earn money otherwise people don't support centralized altcoins.

i suggest you take a look at some of the other announcement topics in this board that are advertising pretty much the same thing as you so that you can learn how to do it better. right now your topic is not introducing the Casino the way you like and it is vague what it offers. nobody is going to want to go to this new site like this.
