what could cause bitcoin prices to go up and down?

[spadormie]

First of all it is because of the high volatility of the market itself that made this coin up and sometimes down. And, also it is because of the dumpster people that just dumps and dumps their coin.

I want to know what you think, what affects the bitcoin price, so we can find out when to sell and buy bitcoin, because now the bitcoin price drops again 

Just like what they said it is all about the market so that bitcoin prices go up and down. Actually the worker that affect the market is the investor and I think they are the one who affect it.

bitcoin is a very valuable coin. This value is lower in the market today. This situation is avoided in the future. If the investors are with bitcoin, the demand will increase if the bitcoin value is higher. People's influence also affects the rise in these values. The monetary value of the coin now stands at a considerable rate. They think that this situation will go away and rise to a higher value in the future. Wait for you. In the future, this situation will be neglected and the value will be higher.

bitcoin prices are influenced by various things, ranging from issues or news that is then dump or pump deliberately by someone and many more to influence the price of bitcoin

[Pinkris128]

More the demand, higher will be its value. Value can increase when popularity  of exchanges increase, exchanges are access points for bitcoins. When exchanges become more people, more people will be using bitcoins due to the ease of accessibility.

Yes the change in value of coins in the market was depends on its supply and demand. Thats why sometimes we experience fall on its price because of low demand. The more invetors comethe higher it value will increase. But sometimes people keep holding which leads to fall of its price.

As my opinion this situations are very normal sometimes bitcoin price pumped up so that the investor's will earn profits through their investment. And sometimes bitcoin price decreasing in order to give a chance to the Investor's to buy bitcoin in a very low price. This is how good thing to invest in bitcoin if you have fully understand the flows and process of bitcoin.

Dumps and dumps? or pump and dump? A lot of things besides the high volatility, news are also affecting the price of bitcoin. If there are FUDs that are spread like those big amount of bitcoins transferred to an exchange wallet, it is causing people to panic and makes the price lower.

[doodle07]

It will be the demand that could cause bitcoin price pump, because of the limited supply which is only twenty one million only to be exact the price would definitely go up for the demand is high, yet another factor that deeply affects the price is the media and others like governments and banks that influencing the mind of the potential investors to not invest because they might be get scam.

中日韩的监管影响不大，价格暴跌，是有“超级大庄家”在操控，在打压比特币的价格，打压人们对比特币的信心和期望。

I think this is their strategy (big investor) to get cheap price, that is why they want market to be bearish. And when they feel they already enough, they will pump coin and make profit again.

The existence of negative news about bitcoin, is one of the causes of the fall in the price of bitcoin. Of course, there are other reasons for the decline in the value of Bitcoin. Regulatory uncertainty, concerns over price manipulation and market sentiment all weigh on cryptocurrency.

Price manipulation, panic selling and other's bad news has caused this bitcoin to go up and down. Exactly the negative news affect the price. However, with the demands on btc could increase in bitcoin prices.

1. Supply and demand relationship（the main factor): the greater the market demand, the price will naturally rise
2. The degree of market acceptance: For example, an application of Baidu before, and Google China accepting bitcoin payment, is a strong signal, so it goes up.
3. The government's policy system and response: For example, there were some proposals from the United States in the past, Bitcoin could be used as a sponsor in future elections, so Bitcoin rose.

[Piggymonster]

I think the factor that affects the bitcoin price is base on the law of supply and demand, the same way the price of the goods sold in the market, the gold and just everything else is determined. The countries that banned bitcoin affects also the demand of bitcoin that is why the price will decline. The basic trading is to buy low and sell high, just always check the price of bitcoin so that you can decide when to buy and when to trade. 

[Ava Duvall]

It is bound to fluctuate.
Bitcoin and cryptocurrencies are not backed by any financial system to keep the price sfable.
Volatility is an intrinsic quality of cryptocurrency.

You are correct. It always changes and yes it is downside that there is no financial system to keep the price stable, but at the same time, bitcoin gives you a lot freedom.

[kingai]

I think factors like
government regulation of cryptocurrency,
Media hype and trader enthusiasm and political and economic upheaval can cause bitcoin price to go up and down

[billionaireSHS]

Sometimes I think that this is because of investments, because as long as investors invested in bitcoin, theres a possible rising of the value or price of it. In contrast, if investors were no longer invested in bitcoin, ofcourse the price of it will fall down.

[Jocuserious]

Actually investment people have been confidence about Bitcoin price,it will definitely increase.but need to wait some panic time.bitcoin price failed start 2018 and I hope this year last come back again Bitcoin price up.

BTC´s nature. Its a pump and dump scheme.

[sindjica]

This is really good question. But it could have so many answers tho.
Supply and demand could be one problem,

Government regulations,

China banning every crypto exchange, mining etc.

So the main reason is probably that Asia isnt strong like it used to be, cause of regulations and bans. Who knows what people in their countries now think about Crypto overall.
