This is a helpful image for easy-to-understand web3. As you can see on the image, web3 shows "decentralization" compare to web 1 and web 2 which is most (probably all) are centralized, controlled by a central entity or company.
There are already a lot of examples for web3 right now, that some people already using, most of them are ofcourse using blockchain, cryptocurrencies involved.

There is already a lot of alternative with Ethereum right now, one of the most popular is Solana as it is a layer 1 protocol and very unique as it is different from other EVM compatible.

I am also a supporter of Solana since starting of 2021 as I am using most of the platforms under Solana especially their DeFi platforms, yield farming, staking, and NFT platforms. Ethereum for me is for whales only as transaction fees are quite expensive but this does not mean I don't support Ethereum anymore, this is just a temporary problem of Ethereum for me.

There are already a lot of ways to stake your Bitcoin these days, but you will use another chain, not the Bitcoin network alone.
There is some alternative chain where you can wrapped your Bitcoin to a particular chain, like in Ethereum/Solana/Avax/BSC, what will happen is you will bridge your assets from one chain to another, for example, the Bitcoin, you will bridge it to Ethereum network and now you can use your Bitcoin as wrapped to Ethereum network.
Then this time, there is some platform that offers staking wrapped Bitcoins, and now you get incentives.

For me, as a normal user of Bitcoin, nothing more especially if you know the basics, how to send Bitcoin, how the transaction or fees work, and different kinds of bitcoin wallet, or bitcoin wallet addresses.

But on the other hand, since I am also a developer. The development that involved codes is the hardest for me, like creating some app that is related to Bitcoin or connecting/integrating some app to Bitcoin.

To be honest, I made a huge lot of profits for the year 2021 alone compared to the past few years since I started with cryptocurrency. It's really different now when you are well-knowledge, you know what to do. For the past few years and past bear market, I learned a lot of lessons and applied them for this year.

For the altcoins I invested past year or this year, most of them I already took profits, most are partial. Taking profits is not always a bad choice.

There is a lot of yield farming or staking these days, especially if you will use stablecoins, it's safer because you will convert to stablecoins to avoid such volatility or worst bear market.

Another thing is if you are a fan of some altcoins, especially mid-low caps. It is much better to move them on high market caps coins such as Bitcoin or Ethereum. It is proven before that the percentage of drop for some high market cap coins is lesser or the bounce is high compared to some low market cap coins.

So what now? If ever this is true or not, what can we do about it?
I saw a lot of people speculating that once the Satoshi wallet will be active, we can see a massive dump of the price.

But for me, I don't think so, it is possible but that's how Bitcoin works, how the wallet works, owner of the wallet got the decision at all.
Overall, it does not matter at all anymore.

EMA for me, but to be honest these two indicators are for moving averages, there is just a small difference for them. As I saw also on some traders, the most common indicator for moving average is EMA (Exponential Moving Average).
Overall, this is just an indicator, which will help you to decide and analyze the chart, it's like an ad-on for me because there are also a lot of things to consider just like @hugeblack said (Support and Resistance) which is I agree, I also want to add the volume and momentum.
But since we are talking the moving average, support and resistance is much relevant.

For the past few months, most of the predictions I saw were on the bullish side, from 2021 up to the year 2022. Remember the famous model for Bitcoin price, the Stock 2 Flow model by @PlanB of Twitter, as it is expecting Bitcoin to reach $100,000 before on 2021 - 2022 range. So, for me, this is still a high chance of $100,000 for the year 2022.
But then again, don't over to confidence as we saw how to bear market on cryptocurrency affect the market.

I want to ask which is your much prefer the platform to use when trading futures?

There are some trading platforms that you only need collateral (could be any cryptocurrency) and you can trade in futures without having particular pair like USDC/USDT.

For example, in Binance there is a Cross/Isolated margin;

If cross, your balance in your future wallet will be used all and possible to liquidate.

If isolated margin, only the amount you set when opening your trade will be liquidated.

And on Binance, you can only use USDT to deposit in USD-M.

On the other side, FTX Exchange which got a sub-accounts feature if you want to isolate your fund and you will transfer a fund to a particular sub-account if you only want specific funds to liquidate since FTX is using cross margin and the same leverage per sub-account.

So, for you? Which is much better if you already tried to use this kind of feature trading futures?
Sub-accounts or Binance like trading futures?

Coinmarketcap got a section for this - https://coinmarketcap.com/events/
But for me, it's not really more information as it is not their main use, but you can still use it and use multiple platforms such as Coinmarketcal (much advisable).
There are a lot of new platforms now, I can add Coinpredictor (https://coinpredictor.io/calendar).

My advice is always to verify after using these kinds of platforms, like checking different social media or announcement platforms of every project you found, like checking their Twitter account or telegram or discord to verify if this platform listing is legit.

I am bullish on Polkadot's parachain auctions. The first batch of auctions went well and a lot of DOT collected is good enough. Winners are also quality of course.

I have tried to contribute also to the Acala network by using the Parallel Finance crowd loan platform. As Acala Network won, my choice went well. Another thing is Binance also offers para chain auctions in which I participated and contributed to some projects.

I love joining on parachain auctions because if the project is lost, your DOT/KUSAMA will automatically send back to your wallet.

For me, back in 2017. Before the bull run started I was already introduced to Bitcoin, and it was also because of Facebook and internet friends also. Doing some airdrops before and participated on some activities with shitcoins but before that, I first used Bitcoin to do some tasks online and was paid with Bitcoin.

I'm really glad that I have known Bitcoin before, lot of things changed especially how I value freedom and privacy.

$19,000 for me is very impossible. It was already tried before when we dropped to around $29,000 after creating an all-time high a few months ago.
For me, for what dumps happened recently, it was only a pure correction and for me, it is a healthy correction because look, it is bouncing after dump and the percentage of dump is not too huge compared to last 2018 when the bear market started.

You can try also it here in the forum, try to create a thread and find someone to work with you, and pay them with Bitcoin.
It's good to find here because they are already aware of cryptocurrency or about Bitcoin.

You can try on this section: Bitcoin Forum > Economy > Marketplace > Services

Ask for their portfolio or previous works, beware of scammers.

There are a lot of use cases for CAKE token (pancakeswap token).

Controlling CAKE supply

Uses of CAKE token are like in LOTTERY, VOTING, YIELD FARMING, etc.,
So those CAKE tokens will burn especially if they will use in the lottery.

Visit this page, which is the tokenomics of CAKE: https://docs.pancakeswap.finance/tokenomics/cake/cake-tokenomics

It talks about how their token is distributed especially the emissions, burnings, rewards.

You can try to use this: https://www.coingecko.com/en/categories/metaverse

That is for the category of Metaverse under Coingecko.
My advice is to try to do research first on high market cap cryptocurrency that is related to Metaverse. Your risk is less here, so your funds are safer than investing in random crypto.
Another thing is, since I am not a fan of Binance Smart Chain (BSC) ecosystem, try also to avoid altcoins that is built on Binance Smart Chain (BSC).

Bitcoin and Ethereum are only for me on the list. To be honest, I don't see any good future for Binance Coin, Cardano, and Dash.
Once Ethereum will solve its problem about scalability, for sure other alternative smart contract chains will start to lay low, like Binance Coin and Cardano. Other altcoins is really far from Ethereum in terms of development and project itself.

I am starting to look forward to decentralized cloud computing projects.
ANKR is one of them. For me, ANKR will also start to join the trends once decentralized cloud will start to pop. With the trends of the metaverse and NFT, for sure some of the projects or platforms about metaverse/NFT will start to use some decentralized cloud.

I remember some projects that are about AI a few years ago and yes, most of them are trash and become a ghost after the 2017 bull market.
And look, this year they started to show up when the Metaverse or about NFT projects started to rise. And yeah, just a pump and dump only, just to make money.
