We are expecting something based on the events on the market as it had happened before like Christmas or Thanksgiving last month when the price fell as well.
$24,2k is a new ath for now but there will be some attempts to break $25k where the resistance will be waiting, and probably the first actual correction after all this rally.

At a time like this when bitcoin reaches its highest price, the best option is to buy altcoins, because the opportunity to get a profit is higher than buying bitcoin at the peak of the price. However, who knows that it's the peak and it won't climb higher? I thought the ath was $22k but it turned out to reach $23k then $24k as the new ath, it even not the end of the year, and what will happen in 2021 as most of the market may reach a higher point.

A layman doesn't have to understand how bitcoin works to be able to use it, all he needs is to download the bitcoin app wallet on the store and buy bitcoin on exchanges.
Volatility is a better reason for people to not involved in bitcoin but time has proven that the value of bitcoin continues to increase rather than decrease, so it is suitable for a long-term investment, simply hold it for ten years and find out how much it can grow compared to put it in the bank account or any other investment.

During the bull run, we are so excited and predict that bitcoin will multiply and reach a certain point, nothing wrong with it as the pattern of the rise and fall of bitcoin seems to tend to repeated although not exactly in the same way. If it's true, bitcoin should reach a new ATH in 2021, one year after halving,  and the price will plummet in 2022, the next halving in 2024 and a new ATH in 2025.

I concur, banks are under the supervision of the authorities, so they do business in a much better way than exchanges compared to the exchange that issued USDT. in this case, Germany’s Bankhaus von der Heydt (BVDH) has received approval from the regulator BaFIN to issue tokenized bonds called EURB. Euro stable coins EURS developed by the Maltese startup called STASIS as an EIP20 standard token on the Ethereum platform in 2018, more competition which mean the quality of service will increase.
Moreover, Bankhaus von der Heydt has partnered with SatoshiPay as a cryptocurrency payments provider to integrate the regulatory complaint EURB into their network.

The sudden upsurge over $4000 within 2 days is surprisingly impressive, the price rise from $19,4k and thought the peak will be at $22k but it turned out to hit $23,777 as the new ath. Then bitcoin price quickly dropped within minutes to $22.4k right now, it isn't clear what is the next support level and the resistance will start to form after a strong resistance such as the current condition.

It's not a new thing or an early sign, crime using bitcoin is happening every day, as people will use everything that has value as a medium of exchange for a good or bad purpose.
The main thing that we have to focus on is the government's response to crypto because many countries have regulated bitcoin whether as an asset or commodity or as an alternative digital currency. It would be better if regulations allow the adoption of bitcoin as a currency for direct application as a means of payment, but as long as it does not hinder ownership or trade the cryptocurrency isn't bad as well.

The price still in the early phase after successfully break the big wall of $20k, the next resistance probably around $21,5k-$21,8k before bitcoin reaches $22k.
However, the price will climb higher in the short term and in the long term, hopefully, the market still holds on a little bit longer than just decide to massive sell out.

The price keeps rising beyond $21k as the ath hit $21,464 on Bitstamp and the price at $21,323 right now.
We can expect the next target is $22k and the resistance levels around $21,5k-$21,8k.
Bitcoin $30k is probably achieved in the next year as the correction may occur after bitcoin reach the ath, some predict 30%-35% retraction.
However, $100k still too far at this point, not impossible but there are steps to go through like $30k - $50k - $75k - $80k, the great resistance will be waiting there and the market needs more investors than currently.

$20,350 right now
and $20,440 the new ath based on Bitstamp
Quite amazing how the resistance level collapse at once after bitcoin succeed to break $19,8k today, it may keep going to reach $21k soon.
Meanwhile, we can rejoice for the new all-time high and hopefully it will sustain above $20k.

People discuss the price swings and prediction because it's fun to do and profits have driven us to get involved in this race, whoever can predict it right, can sell at the right time to acquire higher profits than others, simply as that. Even people have been doing this for a long time in the traditional market like the stock, we are looking for the reasons, cause and effect relationship whenever something happens or why it doesn't fit our expectations and prediction.

The sense of urgency to recover the loss in a short period of time is one of the reasons why you make a hasty and wrong decision.
You should set the goal, how much (percentage) you want before selling the coins, and vice versa set the stop loss, don't let your coins in bleed position for a long time and fall too deep, if your research indicates it will fall and will take a long period to recover, sell it at once.
And the main point is to choose the right coins, it's something that we have to do, due diligence, to determine which coin to buy and sell at the right time.

it seems unrealistic at this time, imagine people said bitcoin will reach $20k back in 2010 when it just launched, did anyone say that was unrealistic? Probably yes.
Nonetheless, no one can say for sure that bitcoin will ever or never reach that point, there is a reason and potential to achieve that price such as more adoption, supply and demand. If fiat currency continues to be eroded by inflation so that its value is depreciated, it is not surprising that the price of commodities such as gold has continued to increase for thousands of years, in contrast to bitcoin, which the price increases rapidly due to various reasons.

We always refer to the whales or big boys who have millions of dollars to spend in the market in order to manipulate and influence how the market moves at their will, but that isn't always the reason for people who can't make profits, it is more about intelligence and strategy to predict the market.
Whoever can survive and last longer in the trading battlefield obviously have a great methodology and strategy to achieve the goal.
The question is what do 1,6% of traders do differently?

People who know to take advantage of bitcoin opportunities make more profit compared to traditional banks. However, bitcoin doesn't always hit a high price in the same way as this time, the volatility is a problem that cannot be resolved so far because of the large number of bitcoin whales that can sway the price of bitcoin. You have to be very cautious to pay attention to the movements and activities of the bitcoin market to make the right decisions, moreover diversification is a good thing just in case something undesired occurs, after all, not everything can be paid for using bitcoin, sometimes it requires cash and withdrawing from exchanges also requires a bank account.

The Bitcoin pattern has been repeated several times in the last 2 months, trying to break the $ 20k resistance level. The bulls are still not safe here, it drops towards the triangle support and consolidates to find support again to eventually break up. Bitcoin is obviously against a big resistance around the $19,4/6 levels which won't break easily and the attempt to break $20k still not seen as bitcoin has not hit above $19,5 again.

Top 20 coins on the market cap provide a better chance for beginners to trade without having to go through too much hassle to do the research, the price tends to follow bitcoin path to increase or decrease almost all the time. Just make sure to always check the trading volume on exchanges and the trend on the market, whether those coins have the demand to push the price higher or will be decline shortly.

Satoshi was right, we can assume bitcoin as a collectible or commodity if we compare it with stocks that have dividends.
The commodity isn't always meant to be consumable, you can't consume gold but it is a commodity, commodity is a useful or valuable thing. In economics, a commodity is an economic good that has full or substantial fungibility; that is, the market treats instances of the good as equivalent or nearly so with no regard to who produced them. The price of a commodity good is typically determined as a function of its market as a whole. source
Collectibles:   May have aesthetic or   emotional value but derives its pricing from its scarcity (supply) and the perception of others that it is wanted. source
However, bitcoin meant to be an alternative payment method، as a means of payment, as a medium of exchange, in short as a currency.

what conditions threaten the bitcoin network that we have to defend it to the death? is it a 51% attack? is it the regulation? or quantum computers?
I believe that people with power (funds and knowledge) i.e. the developers and miners have been working so hard all the time to ensure that the problem solved and also provide solutions to problems that may occur in the future. Bitcoin has been growing rapidly over the last 10 years and there is more positive adoption of bitcoin in the world of traditional finance, even some countries are classified as bitcoin-friendly. every problem has a solution.

In that case, we have to choose some coins that have good potential such as bitcoin, altcoin, ethereum, waves, monero, nem, and so on. 10% isn't so big to achieved and may take 1 week or 1 month to reach it, depending on current market trends. For example, bitcoin fell to $17,6k 3 days ago but managed to increase up to $19,4k yesterday, so it has achieved a 10% increase. Nevertheless, limiting profits to just 10% is indeed an advantage, but some coins like bitcoin have the potential to grow more than that, so we can wait a little longer to take 20% or 30% profit.
