Correct, sell at the bottom is the worse decision, unless you are a trader, it's still profitable to buy and sell in this red zone.
Cash out at the peak is the common sense for traders, and this is the right time for buyback.
However, if you miss the peak due to hoping for a higher rate or don't have cash right now to buy more coin, nothing to do but hold.
Whatever coins that you have, btc, bch,eth, xrp, xlm, eos, ltc, dash or xmr, just hold and wait for the market to recover.

Many factors that can affect bitcoin price, bitcoin futures is one of them as investors can slightly manipulate the market and trigger panic sell. CBOE showed that it saw open interest during the June's settlement 1,412 contracts which is worth 1,412 bitcoin which will make it difficult for the bitcoin market to be highly influenced by that existing number of contracts.
That's not entirely true, contract holders may just buy 1,412 contracts but they can buy and hold bitcoin as much as they want, then massively sell out ahead of the expiration date.
or maybe we just exaggerate the value of bitcoin, whether it's the real value of bitcoin or just temporarily settlement, waiting for another chance to rise. Only time will tell.

It's unbelievable, how could mining fee deducted from investors? and many of them cannot withdraw their right due to high minimal limit to withdraw and lack of information about hashflare maintenance costs,
here the information if you want to withdraw:
Each withdrawal is a subject to a transaction fee, which is paid to the blockchain for transaction processing and confirmation. Currently, the following withdrawal minimums are present:

minimal BTC withdrawal is 0.05001944 BTC, where 0.00001944 BTC is paid to blockchain*;
minimal ETH withdrawal is 0.1006 ETH, where 0.0006 ETH (in GAS equivalent) is paid to blockchain.
minimal DASH withdrawal is 0.1003 DASH, where 0.0003 DASH is paid to blockchain;
minimal ZEC withdrawal is 0.10003 ZEC, where 0.00003 ZEC is paid to blockchain;

The falling is real and already happened since early February drop below $10K, it's inevitable since the market fluctuates precipitate.
The question is: when the price will recover above $10K? We just have to optimistic regarding mid and long-term predictions for crypto markets. It's been 4 months since the first time bitcoin price plummets below $7K in February, it may take another 6 months in the uncertainty due to some unexpected events such as exchanges hacked, Japan's financial regulator issued new improvement₁ for crypto exchanges against money laundering, and suspected market manipulation₂

Pretty big lose, 0.2 BTC just because of neglecting a common thing for wallet backup. I used to use SMS 2fa for blockchain wallet, but not anymore since I've moved to electrum, a better wallet with various advantages and features, just write down all the passphrase to a book and no need to worry if you lose the phone.
ever lost all my phone data once after accidentally reset through email, what makes me worry is google authenticator to access some exchanges accounts.
However, there is an option to reset 2Fa by click on "Lost Your Google Authenticator?" and manually submit Google's 16 digit-key, just follow all the instructions to regain access to your account, but maybe some sites such as binance₁ require you to provide id, passport or driver's license and then take a selfie holding your identity card.
Many two-factor services will give you a set of codes that can only be used to access your account once. After each code is used, it's gone. Most of the time you can access these in the same place where you change your two-factor authentication settings to begin with.
You should definitely print them or or write them down and keep them in a place where you can find them. Ideally, they would be separate from your phone, perhaps in a fireproof box or safe with other important paper documents.₂

Seems like some series of unfortunate events happen in the crypto world cause the price to plummet, the price may drop below $6K level, it's 6065 at the moment on preev and 6094 on cmc. It's a good sign for us to buy more coin, due to bitcoin may fall to the lowest level and will rise sooner or later, as mentioned in the article.
People turn around and bid more and more and more.“It is going to be really interesting to see where all the cryptocurrency markets are at around August, that seems to be when things really start to take off.
Buy now and wait till August, but acknowledge the risk before invest what you can't afford to lose.

I won't say Hitbtc is a very good exchange. It maybe not a scam, but too many cases of pending withdrawals, hacked accounts, and poor support to answer all the tickets. Those are enough reasons to be careful and step aside.
You can find a lot of people share their experience with this site and give negative reviews.

https://steemit.com/hitbtc/@gabrielmotta/why-is-think-hitbtc-is-a-scam
Furthermore, Hitbtc rated 2.21 on http://bittrust.org/hitbtc
HITBTC IS NOT SCAM!!! But there were some issues in December.

Basic thing; acceptance.
Only a few countries, cities, places where we can spend bitcoin in store or pay services. Japan seems the best place for
Next thing that missing is scale transaction, even though bitcoin acceptance increasing and many stores accept bitcoin payment, it still a problem due to unconfirmed transactions takes a long time to be confirmed which leads to increased fees.

Here some information that maybe help.
If you live in Luxembourg, there are some restrictions:
Luxembourg has an outright ban on slot machines, but gaming machines are permitted at the sole licensed casino and account for a vast majority of its revenues.
A regulation for online gambling is also under discussion, but there is no substantial progress since this issue was mentioned in 2012.
REGULATED CASINO GAMES
Terrestrial:Slot machines and semi automatic games, roulette, blackjack, craps, punto banco, stud poker, trente-et-quarante, Hold’em poker, Ultimate Texas hold’em poker, la Bataille, Texas hold’em poker and Omaha poker 4 high.
Online:Only lottery games are available as nationally regulated products.
There are no legal online gambling offers in Luxembourg (except a limited offer of the Loterie Nationale with a maximum bet threshold per week of €250) ₁


There are restrictions to play in online casinos, depends on which country we are talking about.
However, it can be avoided by enabling VPN.
Not sure in China, but US citizens probably can play[2]

I'm curious as well, how did it happen? Mostly through email-id registered to blockchain as my friend ever experienced the same thing.
But the most important, whether Op did all things to secure his wallet such as asked above.
2FA enabled should be able to prevent an easy access to your wallet, use a message verification to notify yourself in case there is an act to hack the wallet.

Seems like Bithumb has noticed hack act since 4 days ago when they were transferring all of the assets to cold storage, or maybe it just lucky move.  https://twitter.com/BithumbOfficial/status/1007873716758327296?s=19
However, what we do know is; hackers stole XRP worth $31 Million, two facts: it's not bitcoin and the amount isn't so big to bring Bithumb down, they assure to cover all the losses. So, why bitcoin would be affected if the stolen coin was XRP? it's a minor loss.
Bitcoin price is $6750 atm

Two smart strategies from the creator, limited to 21 Million and halving every 4 years ensure bitcoin price increase over time.
He knew that bitcoin price will be overwhelming in the future, dominate the market as the first cryptocurrency which is highly valuable.
Though we can't predict the exact number if bitcoin price by the end of the year, but nothing to worry if we believe in the power of bitcoin as the freedom of choice. so, I dare to say; bitcoin can recover to $20K and reach $60K, just time matter until it becomes a reality.
Another reason to believe is; bitcoin industry becomes too big to fail, calculate how much resources has been spending to support bitcoin entity, mining hardware, exchanges, etc.

Those two reasons are enough to stand back from cloud mining or even mining by yourself.
Bitcoin difficulty keeps increasing due to many big companies join into this industry such as GMO in Japan has been developed and sell 7nm bitcoin mining chips which give 24 TH/s.
GMO miner B2 will be sold through the company’s subsidiary in Zug, Switzerland, according to Nikkei. They will be on sale starting Wednesday and orders will start shipping from the end of October, as news.Bitcoin.com previously reported.

The price for each unit is “announced monthly,” the publication added, revealing that the “sales price in June is $1,999.” Itmedia described:

The price for the June release is $1,999 (including power supply unit, excluding tax). The sales price is adjusted monthly according to demand etc. The number of shipments was kept private.₁
Imagine how much the difficulty will be over time, it would be a disaster for miners if bitcoin price doesn't catch up above $10K-$15K.

[1] https://news.bitcoin.com/japans-gmo-specs-price-7nm-bitcoin-mining-rigs/

Bitcoin price falls from $20K to less than $6500, loss over 50% of its value.
Whatever goes up significantly in a short period of time, will fall soon.
Bitcoin gains the momentum from October 2017 to February 2018 and corrected gradually since then, slowly decline from March to June, so maybe it will recover over $10K in the next month after mid-year.
What makes it possible is new trading platform developed by Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange (NYSE) for large investors to trade bitcoin. Once again, big whales will enter the market, the wave will come such as the last year. Read more here: https://bitcointalk.org/index.php?topic=4460961.msg40083147#msg40083147

A good idea to develop it, may I ask some questions?
- is there any implementation of this software, become an active exchange right now?
- is there any limitation if which country can use this software, refers to kyc, banks account, law authorities?
- how to make sure, this software is safe for the non-technical person? A guarantee that there won't be any leak or bug inside which can be accessed by the third party after someone success develop the exchange using this software.
- is it worth to buy this software? have you tried it to launch an exchange? How is it going?

Bitcoin futures isn't a fresh meat for us, it may not change the market movement significantly but give an option for stakeholders to manipulate the price, considering resource they have to do that, investors can buy millions of dollars and dump all of theirs at once in the end of the contract's deadline.
On the other side, ICE plan is a good sign for bitcoin, as ICE will develop an online trading platform to buy and hold bitcoin for large investors, people will be ready for the next big thing. But we don't yet, whether it can affect the sustainability of bitcoin's price in long-term or just another pump and dump situation.

Here another source to add more information about it.
ICE, the owner of the New York Stock Exchange, has been developing an online platform to buy cryptocurrency
The trading platform would "allow large investors to buy and hold bitcoin," the report found.

ICE first entered the crypto market via a crypto data feed, which went live in March.
The exchange operator, according to the report, has also explored swaps, another financial instrument, which would be linked to bitcoin.

Still, if ICE were to follow through on its reported plan, it would be the first established equities exchange operator to launch such a venue in the US.

The venture would potentially have a big leg up over existing crypto-exchange venues which lack the mature market structure of equities exchanges like NYSE and Nasdaq.

The government can create a digital form of their national currency, such as might happens in some countries:
- Ecuador, issuing of a national cryptocurrency, Dinero Electrónico, in 2015 as part of the country’s monetary laws.
- Tunisia, making instant payments worth fractions of a Dinar, at almost no fees at all
- Sweden, not to be outdone, the Swedish central bank, Riksbank, is currently working on a digital version of the Krona. The eKrona, as it has been called, is slated for release in 2018.[1]
Sweden is the most cashless society in the world, it has been steadily moving towards a completely cashless society for years. Cash is now used in less than one in five of all cash transactions in stores.[2]

If the government aims to control money flows in the state, doesn't necessarily allow people to trade anonymously, they will completely ban other cryptocurrencies such as happened in China.

Oh, thank you, I didn't know about it. Will read more about 51% attacks
More information:
51% attack refers to obtaining 51% of the bitcoin network's hashing power.
In theory, obtaining a majority of network power could potentially enable massive double spending and the ability to prevent transaction confirmations, among other potentially nefarious acts.
However, this would take a huge amount of expense and effort and, should a big double spend be attempted, the data would likely appear on the block chain for all to see.
Worse, such an attack could possibly destroy the integrity of the system as a whole, causing the price to crash. This is not something anyone with a vested interest in bitcoin would want – especially miners, whose profits depend largely on the price of bitcoin being high. Hence, there is no real incentive to attack the network.

https://www.coindesk.com/51-attacks-real-threat-bitcoin/

where did this figure come from, 51%? What kind of method?
Please enlight me.

Why so sure that other cryptos are very vulnerable to such attacks, once again, what kind of attacks?
The bad guy can do anything to steal cryptocurrencies, not always through online hacks, as there are some cases of "bitcoin rich" were kidnapped and demanded to be paid using bitcoin. More information here: https://cryptovest.com/news/criminals-move-from-hacking-to-kidnapping-disturbing-tales-of-latest-acts/
That's why, do not let others know that you posses so many bitcoins in your wallet, mix it with chipmixer and divide to some addresses.


This problem can't be solved, the evil will remain in this world until the end of the time.
