The price is declining because a lot of coins, including Bitcoin, have been heavily overbought in early 2018. At a time when prices were so high, it attracted more and more new investors. These were the people who just wanted to make money as soon as possible. In fact, they didn't believe in cryptocurrency and in their future for real.
After such a take-off of the price, a deep correction naturally takes place. At this time, those who really didn't believe in crypto currencies start selling them for fear that the crypto market and all currencies have come to an end. Therefore, the price drops lower and lower.
This whole situation is fueled by some negative news and the world economic situation.

I'm happy for you!
Bitcoin was created as a protest against the existing banking system. Apparently its creator (or group of creators), just like you, felt the pressure of the banking system with its perpetual commissions and delays.
And as a reward for dislike of banks and faith in Bitcoin, you will soon receive a multiplication of your investments. Be sure of that.

Unfortunately, most don't understand that now is a great time to buy and increase crypto currencies.
People are so afraid that the end has come, that they are not even able to think sensibly. Some of those who held on to the last are already giving up and reflecting on the sale. But if you didn't sell for so long, what is the point of selling now?
Buy now, because, then such prices will not be in the future.

Of course not. What we see now is a terrible manipulation, which is now turning into a panic sale. Just keep yourself in hand and don't sell your bitcoins. Remember that such a fall in the course is not the first time and after the fall there will be new price ups. Don't let your fear take hold of your mind.

Witty, but I would like to correct something.
I would replace the word "bitcoin" with the word "crypto market".
After all, let's be fair, a terrible manipulation is simply present in the crypto market. And the game in this market is like a casino.
After all, when you buy a regular cake in the store, at an incredibly overpriced price, you don’t blame the cake? And such a high price for it can be created artificially, by a store or by increased demand. And no one forces you to buy THIS cake and at SUCH a price.

Needless to say, everyone is disappointed. I'm not disappointed. From the beginning, when I started buying cryptocurrencies, I understood a few things for myself. 1- invest only the money that I am willing to lose; 2- when I double my investment, I will take my first investments back; 3- the crypto market is highly manipulative, so prices here can rise and fall very much; 4- I believe in crypto currency and bitcoin.
It is thanks to the implementation of these items now I'm not afraid. Yes, I worry like everyone else, but I also know that time will pass and the price will recover.
Of course, for those who bought Bitcoin for $ 20,000 and have not sold it yet, the situation looks very sad. But guys, you have nothing to lose. Just leave your bitcoin alone and after a while you will be glad you didn’t sell it.

I completely agree. That is what I try to tell others often.
Our faith feeds us and the crypto world. Those who came here just to earn money, not believing in the cryptocurrencies and their idea, most likely have already lost all of their investments (or almost all). Now these people are trying to tell others that crypto currency is a scam. With such conversations, they frighten newbies (and not only), who are now generally shocked by what they see.

I want to appeal to everyone who reads this: Believe in crypto currency, Believe in Bitcoin! Time will pass and all prices will be refunded. Just accept the fact that now the price is such and it can fall even lower and believe that after a fall, the price will rise again and surprise everyone!

In essence, the creation of Bitcoin was the beginning of the crypto world. And all those "high-tech currencies" and all developers and all traders are obliged to the creators of Bitcoin and Bitcoin itself. Don't forget about this invaluable contribution of Bitcoin. I am sure that many smart people do that. That belief in Bitcoin will not allow it to disappear. There is not a single real reason why Bitcoin can wait for the end now.
But the high-tech nature of other crypto currencies still doesn't make them even equal to Bitcoin. Therefore, now to discuss the issue of the future "superaltcoin", which will take the place of Bitcoin irrelevant.

What do you really want to hear?
Today the market situation is very unfavorable. So if you yourself cant determine for yourself the strategy of work in this market and understand what else you can do, then the best thing is just hold.
The fact is that even if someone gives you good advice (for example, short), you will not be able to use it due to lack of knowledge, practice and skills.
So be grateful to those who give the advice that is right for you. And if you really want to understand what you can do now, then start exploring this question at a deeper level. Look in the Internet, information on how to trade in such a market and study it.

Instincts must always be verified and confirmed by facts, otherwise trading runs the risk of becoming a game of luck. In my opinion, this is unacceptable if we are talking about a serious approach to trade. After all, you must agree that hoped that the price of the coin you bought will soon grow up, because the “instinct” suggested to you, somehow childishly. After all, even if the inner sense tells you that you need to buy some kind of coin, then before buying it is necessary to analyze the price of the coin. And how can it be done if the trader doesn't know basic things? I agree that technical analysis often doesn't work. In the crypto world, news and whales plans have a huge impact. But only knowledge and a keen mind will help to get a permanent profit here, and not instinct and luck.

You yourself write that: "you can do scalping trading and increase your holding by it and gain profit.". That is, you understand that the HODL is a great solution. You should write about it.
Probably you mean that only a HODL is not a good solution. But with this statement it is possible to argue. Everyone chooses for himself the trading strategy that suits him. And if someone decides only HODL, then this is his right. Such a person, for example, doesn't want to spend his time and health on the round-the-clock worries about  buy and sell coins, he will spend his time on his family, rest or somewhere else he wants. And this doesn't mean that he doesn't know how to trade.
Personally, I trade when I want and there is time for that. I like both day trading and long term trading.

I understand you are talking about scalping? If you good in quickly to make a deal and make a profit, then this is excellent. Strategy requires a quick response and high concentration of attention. It is believed that this strategy is the most highly profitable. It is also considered that this is the pinnacle of skill.
Of the minuses I can highlight:
- strong tension caused by increased concentration of attention (the deal usually closes in a few minutes or even seconds);
- high risk to miscalculate and fail;
- the trader must constantly be near the laptop. This noticeably affects the quality of life and health.

Trading and instincts have nothing in common. It's like, "I will go to the exam without going to class and not preparing for it, because I feel that everything will be fine."
OP wrote elementary things, which for 10 minutes can be found on the Internet. If you don't find the strength to do this, then you are simply doomed to failure.
In the end, only knowledge and practice can be profitable. And you play in a casino, just hoping for luck ...

Thanks to the author for describing such a simple and understandable strategy!

I  think bots are a bad idea. A bot is good if you know how it works and you can make changes to its work (correct) at any time. That is, bots are good for those traders who develop them.
Also, don't forget that a bot is just a program created to perform automatic functions. That is, in an unusual situation, this bot can make you bankrupt in a matter of hours.

Nobody will tell you what will happen next. Everyone just has their own assumptions, which can change several times during the day depending on the current situation.
Personally, I suppose that the general price reduction will continue in the near future. The situation with Bitcoin cash continues to negatively affect on the course of Bitcoin. But if look at the picture as a whole, I suppose that at some point the price will push off and start to grow rapidly.

Don't be afraid. There are many articles on the Internet about how to get started. I will highlight several stages for you, and you will be guided by them.
1. Select the exchange on which you plan to trade. For a start, you will only need one or two, and later you yourself will understand on which exchanges you still need accounts for.
2. If the exchange chosen by you doesn't have the opportunity to immediately start a fiat, then find an exchanger through which you can buy a crypto currency on fiat. On the exchanger you will need to specify the address of the wallet for the transfer of cryptocurrency. This address can be found in your wallet on the exchange.
3. Now is a great time to buy currencies. I would recommend to buy Bitcoin now. Then you can buy for Bitcoin any currency that is traded on the exchange paired with Bitcoin.
4. Constantly study all the necessary information. Training is the main stage for the future trader. After you learn the necessary information, start practicing.

Well, I think that now really bearish time is coming to an end. I suppose that now comes the final stage - shearing the sheep before growth. If we take into account the psychology of the market, this will be the final phase of the downtrend.

But such people form the basis of the market. This is the  crowd, through which you can analyze the market and it is subject to certain laws. After all, when we talk about the psychology of the market, we mean the overwhelming majority of market participants, and these are ordinary people.
The psychology of whales and large investors cannot be analyzed. These major players act on the basis of their interests and in the same situations, respectively, they behave differently.

I think that you have an incomplete picture. Why do you think that there are no new investors? You must take into account the current market situation. Many investors simply prefer not to trade. Therefore, we do not notice the movement. But as soon as the market situation improves, you will immediately notice a movement, as many will want to trade again.
Therefore, a lack of investors will not interfere with trading volumes on the exchanges. Just let the market recover.

I don't agree with your statement. Airdrop I consider a waste of time. In most cases, you will receive unnecessary to anyone tokens at a total cost of $2 (or so). You can’t even sell them anywhere, unless you buy more than these tokens for your money. But this is contrary to your statement that tokens are obtained free of charge and you don’t need to invest your own money to make a profit from them.
Of course, sometimes there are excellent airdrops, but if we tell the whole truth about them, then it’s quite difficult to participate in them.
As for the bounty campaigns, everything is also ambiguous here. Working in a bounty campaign you risk. The risk is that the wages for the work you have done may simply not be paid. There may be several reasons for this, from the injustice of the campaign manager, to the failure of the project to pay the participants of the  bounty campaign.
It should also be noted that the tokens that you paid for the work at the time of payment may already depreciate greatly (especially in the current market situation).

Earnings on crypto currencies are always risky. Don't forget about it.
