Then this is just an example of hype, which is really common in every bull market. Every bull market there is a new trending way to get high profits and at the same time loss money. So on next bull run, fan tokens may still stay and improved, but I am not expecting it will be the same hype like before to next bull run because there are new niches will come.

OP is worrying about the decentralization here. Where Proof-of-stake protocol's main problem is decentralization. I read somewhere before saying, "It's much better to solve the scalability the decentralization".
This centralized issue is became common issue for POS protocol, not only for Ethereum, there are already lot of protocol already that is in POS and they are working fine, this is just a matter of time.

Because it lures scammers/hackers/illegal money laundering. For sure there are already a lot of people or entity already used this platform to launder money and the government already notice it and this is already their approach to fighting it. This is just a very bad news or day for cryptocurrency community because the essence of decentralization or privacy is getting destroyed.

This is possible but expects the whole market will pump too not only Ethereum Classic. Before we will see this ETC will go with 3 digits, I am expecting that Bitcoin and Ethereum are on their new all-time high.
Or the worst part is the Ethereum POS will fail which got a very low chance to happen.

It's really the market, you just can't say Bitcoin. Because the event we had is about Ethereum and for me, even after The Merge event and Ethereum pumped, I expect that Bitcoin will pump too. But we went on the opposite side and the whole cryptocurrency market went down.
I am expecting this before, the pump happened already before the event and the sell of will happen after the event, "buy the news, sell the rumors".

Yes, but  Binance is considered as a centralized exchange in which you don't hold your keys, your money is in Binance's hands, on the other hand, the alternative is to use some decentralized finance platform where staking is available like Aave or Solend. But you still can't guarantee safety here.
OP must select a platform carefully and the asset that they will stake because the UST issue before on Luna could repeat again on other assets.

I am now curious why the Bitcoin price is dumping now when the inflation rate is rising. At first, I believe that Bitcoin solves this and that Bitcoin is somehow the best solution against inflation for now but we saw the opposite side.
This seems really the effect of a bear market which even though the market tries to recover it's really having difficulty.

Depends on other characteristics of the coin as you only mentioned two.
If there's any way I can make profits or give back my capital, I'll buy it. Or even if it's at a cheap price, I'll buy it too.
But the thing it cannot be sold seems a very big lose just incase especially if this is expensive, which majority of people won't buy it.

There are a lot of groups like these, they are totally free and not greedy.
I already experienced this kind of group but later on, they start to become not free, if you want to stay, you need to pay.

My advice to OP is don't really feel comfortable here, you must also learn by yourself or learn from them because it will help you forever as this group could stay temporary and not stay forever but having knowledge of how to trade without relying on other people is a big win.

This is already given. Scamming people by scammers seems to become a business for them, they scam for a living, I can't stop to think if they can use the money they scammed to feed their family.
Keep in mind that even how huge or small a community, scammers will be there, especially on cryptocurrency market which is most projects are decentralized and anonymous, scammers are everywhere and they can easily do whatever they want.

This seems not training when you tell following some person/entity on the internet with their trades or following their trade signals whenever they tell.

For OP, most starters are always starting to learn trading by their own selves. If the professional training you mentioned is free and less hassle, you can give it a try, just make sure to do your own research too just to verify their lessons.
For me, there's nothing wrong for such training/lessons, free or non-free it will be up to you how you learn.

Trading or converting my Bitcoins to random altcoins before, this was my worst experience when I was first introduced to Bitcoin and cryptocurrency.
At first, I was very happy owning Bitcoin but after that here comes the altcoins that really eye catchy when you are newbie like you don't have yet any knowledge at all. It was all a lesson for me now because seems most of newbies also experienced what I did.

This is not only the basis, you should consider a lot of things not only how their token economics works.
This token economics is just a part of identifying how good altcoin but this is still important though, you should identify it first.
There are some projects that their supply is quite low or decreasing or limited, but on some part of their project is not good like no use cases or product, it's still useless.

And people fighting their random meme coins like Shiba Inu that are comparing to Dogecoin, lol. This is one of the best examples of why Dogecoin is the number 1 meme coin.
Dogecoin for sure will still hold its position these coming few months, until whole market or Bitcoin recovers.

I was curious why whole cryptocurrency market is whole down which only Ethereum has this huge Event (The Merge).
This seems to be expected by the majority, succeeds or failed or if got something issue on The Merge, the market is expected to dump.
Overall, this is still good, this dump for me is just for the short term.

As time goes by, there are a lot of cryptocurrencies are popping up. For me, Bitcoin is already proven by the time, the first cryptocurrency ever made, and always on the number 1 top market cap. For me, Bitcoin will stay but other altcoins could be here temporary? We'll never know, because most of cryptocurrency that popping now are just here to take money from people.

In risk management, you must stick with your plan. Try to wait or let your trade go alone as long as you already set up the take profit price and stop loss price. Some traders tend not to have patience and they always tend to f*cked up their trading plan at the beginning.

Most of these projects are using the same codebase or codes for their smart contracts and they just change the name or what just to lure people again to scam.
This is very worst, people must learn or know first what they are doing before putting their hard-earned money into these scam projects.
This will not end, for sure if this way will become popular and easy to identify as a scam, they will change it again or improve it just to make it looks legit.

Play-to-earn recently for me seems like hype but most of that kind of projects on crypto are normal even before, ICO fever last bull run 2017-2018, NFT and Defi are also suffered from the extreme drop and it's normal because the market also devastated and no one is excused.
The good thing here is the innovation, projects on play-to-earn are still here, company or teams are still learning and developing every day and that's very good for the play-to-earn community.

Include the platform where you will stake your stablecoins and the asset you chose. One of the examples here is the UST before with huge APY on Anchor. The APY before was around 20% and when the disaster started to happen to UST, the value of UST is dropping and the drop could reach -20% in just a few hours or a day. It's not worth it, even if you stake to some centralized exchange, you still can't guaranteed how safe they are.
