I think there are definitely altcoins who will survive in the future. First of all, these are working projects that have a finished product and develop it: Ether, NEO, Cardano, Rippl. Also worth mentioning is Litecoin, Monero, Bitcoin cash. All these coins have great potential and strong, rich and powerful teams. They are also well supported by the community. These coins are in demand and popularity.
Of course, no one knows for sure what is waiting for us in 5-10 years, but these coins demonstrate some stability even in the current situation. They continue to occupy the first places of the top of all crypto currencies. Therefore, for the next 2-3 years, I consider these coins to be an excellent investment.

I think Satoshi Nakamoto is a group of people. I think that creating Bitcoin alone is too difficult. Of course everything is possible, but ... One of the creators of Bitcoin is certainly a genius. It’s simply impossible for an ordinary person to create such an idea and bring it to life.
In any case, I'm not interested in the real identity of the creator of Bitcoin. If he (or they) wants to remain anonymous, then I respect his right to that. I think Satoshi has achieved what he wanted, so more and doesn't get in touch with the world as the creator of Bitcoin.

I believe that it will be so. If you think logically, we see certain regularities. All relationships between people are constantly evolving and improving. With the development of technology, these relationships are becoming more saturated with various technologys. This also applies to commodity-money relations.
Long time ago, people, in order to get what they didn't have, exchanged goods with each other.  Later money was introduced for this purpose. With the advent of money, people have become able to buy what they need. At the present time, money is the most important element of any developed economic system.
Now technologies don't stand still, therefore, there appeared electronic money. It is very convenient. You don't need to carry a wallet with money, and payment can be made for any amount.
Time will pass and crypto currencies will undoubtedly be accepted by the whole society.

I also have my business, which has provided me for many years. But crypto currencies strongly attract me. I'm good at making money here. But I basically saw only an upward movement, and this confused me. Since spring, I have almost completely abandoned my business, so I received the minimum income from it.
But with such a deep correction, I encountered the first time. And I realized for myself that if I didn’t keep the insurance for myself, the time might come when I would end up without a profit. As I already wrote, it is impossible to rely on 100% that you will earn well on the crypto market.
Therefore, I support the OP in that you should not give up your main job, which brings money to live on.

I agree with this addition. But my answer was based on the question. If it is read in isolation from what the OP is asking, a different impression may be made. He asks what strategy to apply for earn money now. And in order to advise a specific strategy, it is necessary to understand first of all what level of knowledge and skills he has.
Of course, a successful trader needs to be able to, know and understand a lot. This also applies to the professional component and also how a person is able to think and work on their emotions.

Well, that you write about it. Don't forget that the crypto market is very volatile, so don't rely on earnings here at 100%. The events that are happening now additionally prove it.
This year, I also, like you, gave priority to the crypto market, instead of my main job. But in the summer, I clearly understood that it is better not to completely give up what my regular income brings me from my business.

I think that now is a great time to buy bitcoins. Of course, it is better to buy gradually, because the price of bitcoin is still declining, so it will be possible to buy at lower prices.
And as the practice of 2017 shows us, it is better to seize the opportunity to buy it in the near future because later this possibility may not be.

I usually buy different coins. But all of them are united by one thing, I see in them the opportunity to earn.
I buy new coins very rarely, because if the coin is new, then it doesn't have a history that can be analyzed in chart. And if I'm interested in some kind of new and promising coin, then I buy it by participating in ICO.
For a quick purchase / sale, I choose volatile coins, the price of which can fluctuate greatly throughout the day. Sometimes I  buying coins, which show significant fluctuations in a few days. But now on the market is very unstable situation, so right now I avoid such coins.

Thanks for the analysis. Everything is very sensibly described. I anticipate a similar situation, but still hoped for a rebound. Now I take note of the new information.

For those who believe that charts and technical analysis is nonsense, I want to ask: What are you guided by when doing price movement analysis?

I think that I can’t wait for an answer, so I just want to write. Only technical analysis and charts can give a real idea of ​​the market situation and price movement. Without them, you generally will not have any idea about the possible movement of prices.

It all depends on what level of knowledge and skills you have.
For inexperienced traders, holding their own coins is best now.
For experienced traders, other possibilities open up. And of course, first and foremost is trading.
If you look carefully at different altcoins now, it will be seen that even now the prices for some of them are quite high. Of course, first of all, you need to consider trading pairs to bitcoin and ether.

Regulation of the crypto market is a violation of the main purpose of crypto currencies. Bitcoin was created in order to get away from centralization, so that no one could take your bitcoin away from you or distribute it at its own discretion. So this is one of the main problem.
On the one hand, regulation should attract new investors to the market, on the other hand, because of this, the  idea of cryptocurrency is being violated.
Personally, I am satisfied with the market as it is, otherwise I would trade on the stock market.

ahaha... You're right. With all of us so often, what choice we will make, we will still lose 

Speaking seriously, this situation is not very funny. There are large investors, or as we call them whales, who play well on human psychology. People are all alike, most of us do the same thing in the same situations, so we are just a crowd. And the crowd is easy to manage, because if the part of the crowd is forced to buy cryptocurrency with psychological pressure, the rest will also start to buy, despite common sense. And vice versa.
Now market participants have been subjected to psychological pressure, and in this situation, many are selling.  Even early Bitcoin investors are starting to think about selling.
I don’t know how you assess this situation, but I see in it a strong planned manipulation and I will not be part of the crowd. Even if I remain an investor for several years, I don’t want to participate in this circus, organized by whales.

When I invest, I don’t listen to other people's advice. Investment is just my decision. I specifically avoid articles, videos and publications that advise me how to proceed. Moreover, I think it hurts when making an informed decision. That is why I independently evaluate the charts and news background, as well as reflect on the possible options for the turn of events, which are not spoken by everyone.
And if I make a mistake, then I will make the right conclusion, since this is my miscalculation.
If I followed the advice of someone and lost money, the only reasonable conclusion that could be made is not to trust someone else's opinion. But I wouldn't know exactly where I miscalculated and what I didn't correctly take into account, since the other person was doing this process (maybe he didn’t do it at all, but he simply invented something and advises everyone).

OP, I wonder how long you have been on the market and how long have you owned bitcoins?
I see from your posts that you know about Bitcoin since 2014. Does such a market situation really affect you so much? I think that you are not one of those who bought Bitcoin for $ 10,000-20,000, so it’s very surprising to me that you lost faith in Bitcoin.
You must understand, large investors sold their bitcoins in December 2017, then they played well all year round, pulling out money from inexperienced newbies. Now it's time for them to get their bitcoins back at low prices, thats why now we see this situation.
In addition to all the clowns from Bitcoin cash staged (most likely also planned) for all the super show, which negatively affects the price of Bitcoin.
And the price reversal will be when people like you, those who hold Bitcoin over the years, lose faith and start selling their Bitcoins. I think this is the plan of whales  .
So don't become one of those who will be overboard of the ship at a time when Bitcoin starts a bull run.

People are the target of bitcoin market. After all, people are market participants.
Actually at the beginning of Bitcoin was created as a decentralized e-currency. No one could control it, could not print it, fake it or devalue it. It was created for people and for facilitate mutual settlements between them.
But over time, Bitcoin has become some kind of tool for earnings. Speculators manipulate its price. Large investors are able to influence the exchange rate.
Unfortunately now because of the created HYIP, Bitcoin is becoming more and more like a collectible item. People prefer to accumulate Bitcoin, rather than use it for its intended purpose.

What? Craig Wright is Satoshi Nakamoto? This is ridiculous. Over the years, there was already a few of Satoshi Nakamoto, but none of them could ever prove it. I'm sure that in the future we will also meet a few Satoshi  .
I think that the creator of Bitcoin doesn't want, that everyone would know who he really is, so he will not reveal his real identity.

Regarding Bitcoin cash, I think that we are witnessing the struggle of the two largest pools for a large market share. So far, you can only see a lot of conflicting information. But I wouldn't rush to conclusions.

Today, there are some very good crypto currencies that are high-tech. But, if they really were as good as you describe, then no one would need Bitcoin anymore. All currencies represented in the crypto market have their own problems. In addition to the individual problems of each currency, I would like to add common main problems due to which cryptocurrency is sufficiently isolated from the real world:
1. Scalability for tasks of a real level of complexity. Companies will not switch to the blockchain until it is proven that it has scalability to solve problems in the real world.
2. The issue of regulation. In order for the world to massively switch to cryptocurrency, some kind of regulation is needed. However, regulation violates the basic principle on which cryptocurrencies are based. Finding a compromise between the need for regulation and the desire for independence will be very difficult.
Once these common problems are solved, it will become clear exactly what crypto currencies are actually needed.
And if I were you, I wouldn't underestimate Bitcoin.

The fact that the price falls doesn't mean that there are no purchases. After all, think  yourself if someone sells, then someone buys. This is true? So for every bitcoin sold (or altcoin) there is a buyer.
So, some people sell thes coins under the pressure of their fear (even if they suffer losses), and another part of people buys coins thanks to the desire to earn (therefore, in the future they will get a decent profit).

I agree with you. I think that those who don't quite understand what is crypto market and what is cryptocurrency are now get upset about. Many people are here to earn money, but at the same time they don't want to clearly understand how to do it. All these people become  ordinary crowd that buys at high prices, because everyone buys and sells at low prices, because everyone sells. Many of these people don't even think about the real reasons for this price drop. Everybody is just afraid that bitcoin is dying 
And only some people know that now is the time to buy.

In addition to hold, you can also TRADE. November 20, the spread of BTC was about $ 500. So those who are scalping, are received a good profit. Of course, such trade requires good knowledge and experience, but it also brings a good profit.
If people don't want to learn to make a profit always, with any trend, then they I can advise for them only hold.
