Based on the demand, supply and play of major bitcoin holders! The more popular Bitcoin has become, the higher its price has risen in 2017. In 2018, the price of Bitcoin began to fall due to a decrease in demand, and popularity began to fall. Now bitcoin has taken its place in the cryptocurrency market. But as soon as some powerful holder enters the market, the price of Bitcoin will immediately change. Chaos will begin again in the market.

We all know that the crypto currency is a decentralized currency so that none of the individuals regulate and control the system and the movement of the price of bitcoin and altcoin. price movements are strongly influenced by supply and demand. however, each individual can make a policy that affects the price of bitcoin or altcoin.

but bitcoin cost depends on deytviya of people. therefore it is quite reasonable to say that he is operated by people.

Every individual does contribute to the total pool of the btc or other crypto coins. But individuals generally cannot drive the price as their are larger institutional players who buy in bulk and this is what drives the prices rise or crash in the market.

The notion that cryptocurrency doesn't need intrinsic value is nonsense, because market value always depends in part upon intrinsic value. “Currencies to be exchangeable have to be backed by something,” Greenspan points out. Without intrinsic value, nobody would have assigned Bitcoin a value in the first place

The market is controlled by all individuals, but no individual has the power to control all.

For individual to be able driving bitcoin in the market, it will need very massive amount of bitcoin.
I think it is not the individual, it is a group of whales who can make the market price going up or down.
The bitcoin value comes from massive adoption of peoples who buy bitcoin, they bought and sold it with higher price.

Despite some theories that Bitcoin is strongly influenced by some interest groups to my opinion individual users still have the biggest impact.
Also, we have whales who usualy hold very large amount of Bitcoins and no doubt they can influence the market but still usually this is exaggerated.
There is no conspiracy theory behind Bitcoin and it's not driven by some special group of individuals but each and every Bitcoin user has its own contribution that is valuable.

Yeah , your words are absolutely true but it doesn't contain the situation that "That guy has a lot of Bitcoin" . So if they have the market in their hand so they can drive Bitcoin and the whole market for sure.

Thats right. Im also not deny that the price of bitcoin is also driven by several groups or even whales with large capital competed with them. but it's true what you say that. individual users have the most important role to drive bitcoin prices on the market. You know the total of bitcoin users in my country? currently reaching 2 million users. it can be seen from the number of registrants on my local exchange sites
