It is impossible for a project to maintain a price in a bear market condition. Because they do not develop a project with a stable price. Of course the project must follow the flow of the market. Even if the project developer keeps the price higher and higher, the project developer must recruit new investors from time to time. This is something illogical in the crypto market. The stock market which is known to be more stable is also bearish.

Yes. They were disappointed with the change of Ethereum from PoW to PoS. Because most of their mining machines can no longer be used. But I can't be sure about this truth, because I'm not mining Ethereum for now.  This is just the information I got in the media.

And you also feel unsure of Luna like other people are not sure at this time. From 10.5$ to 28.7$ you've already asked this, so I have no doubt that you are hesitant to hold on long term.  Most people don't trust Luna, but if you buy and hold on to it for the long term, of course you'll get a huge profit opportunity when Luna's team pumps up the market to convince investors.

As long as I'm using Trust wallet, it's never been hacked. So I conclude that Truswallet is safe to use. But if you use Trustwallet to hold coins long term, it's a good idea to create a custom wallet without connecting to other platforms. So that your wallet is not reached by hackers. Maybe this is the part we should pay attention to to protect the wallet. But the rest is Trustwallet developers have also provided high security on the Trust wallet.

Testnet is a trial. If you see testnet, then you are in test mode. This illustrates the mainnet mode will also work according to the ongoing testnet mode. This is not much different from the beta.
If you create an app, before officially launching it to the public, then you must launch the beta version of the app as a feasibility test.
Likewise on the Ethereum blockchain. Before the official version of the token is released to the public, a testnet version will be developed as a trial.

Maybe I have my own point of view in the crypto market. If market conditions are down, or a bear market is in progress, then most new projects are very difficult to develop. Unlike the bull market, whatever crypto is developed, it will be successful, at least there is a price change after launch.

If Bitcoin is released with the amount of 100k , of course the crypto market will be red like the sun that cannot be seen directly. That is, it has a huge effect on the crypto market.
Maybe MtGox won't let go of all the Bitcoins he owns. Big investors don't brutally destroy the market by selling all assets in an instant, they prefer to create more attractive wave charts, not waterfalls.

Sometimes I also think is it necessary that every digital gold developed by a crypto company should be backed by gold reserves?
This is the same with USDT. If Tether does not have USD reserves equivalent to USDT, and can function normally as a crypto company providing stable value services, then the digital gold company does not have to have real gold reserves either.

Make two-way trades. I think this provides an opportunity to profit in bear market conditions. Unlike the bull market conditions, we can hold the coin for a longer time. However, if the capital is too small, it also does not provide significant value, or spends a lot of time for small profits.

Do not make opinions without analysis, because it can make things worse. High speculation on projects that have actually done scams is also an invitation for people to invest there. I hope crypto users don't get caught up in people's speculations that are too high on a particular project. In general there is nothing wrong with one's speculation, but those who speculate should also look at good projects. At least the project is not committing a real fraud.

Try checking the icoholder site, maybe that's what you want. Or another site is icomarks, crypto-rating. Previously I also used these sites to check the accuracy of a new project. However, this rating does not guarantee the success of a new project.

I can't confirm if it's a scam or not, but when I tried to open a Decoin exchange, I didn't receive a confirmation email to login, so I couldn't enter the exchange. I'm sure this exchange is in trouble, at least they have an error in setting the confirmation email.

During the Ethereum merge process, there was no Giveaway, there was an ETHW hard fork. And I also earn ETHW for the amount of Ethereum I hold. I see today's scammers easily commit fraud, they even make posts directly through our account. This has also gone viral with a BTC giveaway from Elon Musk.

We haven't seen the crypto market truly experience a bear market. The current high price of Bitcoin has allowed most cryptos to survive. Dogecoin can last a very long time with the lowest value. While Shiba has not experienced this. Although the shiba team continues to develop their platform, we will also see in the next bull run when new coins are popularized. Usually there will be coins that die when new coins appear.

Most likely the coin that will make its way to the top 20 is Cake. PancakeSwap has a huge impact on crypto today, especially those who trust the Dex platform more than Cex. Then what coin will go down in position? In my estimation Tron and Shiba.

Polygon, Polkadot, Avalanche, Cosmos, and FTX are also long term coins. I think it has more potential for the future. I've noticed these since their early development, they grow quickly, and hold up well even in volatile markets.

Of course LTC and DOGE are different from Bitcoin. But there are some things that have in common, between Litcoin and Dogecoin can be mined, just as Bitcoin can also be mined. However, Dogecoin does not have a limited supply, maybe in this case Litecoin is the same as Bitcoin which has a limited supply. The PoW protocols of Dogecoin, Litecoin, and Bitcoin are of course different, even though they are both PoW.

I expect $10k price for BTC market, it's more beautiful for bear market. If the current BTC price is bearish $10k, then bullrun with ATH $100k. But we can't say for sure when the bear and bull market will take place. Maybe you can take a look at this story on coinmarketcap, so you can make your own decision.

But I'm not interested in the meme coin even though it has made a splash that has taken the crypto market by surprise. Meme coins are not long-term coins, because every bullrun there is always something new that goes viral in the crypto world.

No exchange is free. Even if the stock exchange implements it, I'm sure that within a month the market will close. But there are exchanges that are free for certain coins, for example Binance which makes free BNB or BUSD transaction fees to internal wallets. FTX exchange with free withdrawal fees for BSC and Polygon. It is impossible for the exchange to make it all free while the exchange needs to pay the blockchain network fee.
If you want to see the trading volume on an exchange, or the level of reputation and ranking of world exchanges, maybe you can check on coinmarketcap.
