Clearly, it has to be Mohammed Lee.

Now really... it's a free market. And an unregulated one. Entities with enough money can still play pump and dump games, whether we like it or not. Information war (and FUD) also helps... them.

I think who control price the crypto market is big investors,   they can control in low price and then to the high price. Everything of cryptocurrency depends on them, that prices go up and down because of the consequences of our own selling btc at a low price.

Nobody control the market. there are some people buy and sell bitcoin, do market transaction. That's make the price can rise up or down anytime. I sure it can rise up again but it takes time.

Whales! those who have large amount of bitcoins in their holdings. They can easily bring down the market by dumping huge amount of BTC. The current volume of BTC in the market or exchanges is relatively small than what is on peoples wallet.

As people has written, there are definitely some people who has a large amount of btc and therefore can move the market any way they want, only requires a nudge to move the market!
and some people say that all these "longs/shorts" are simple "liquidated" by people who move the market up or down and therefore makes money in either direction.
remember the market is still very small! 300b market cap doesn't mean 300b has entered the market.

Depends what you define as control.
If you are talking about the freedom of sending value across borders to anyone you want in a short amount of time, then noone. Noone is controling crypto this way.

But i assume you are talking about the trading market. The people who effectively control the market (and with it the price) the most are the ones who have a massive amount of money and want to control it.
The $-value is purely dependent on the supply and the demand. If a single entity has enough power (meaning supply OR demand) you could consider it a market maker and therefore also controlling the market.

The more mature the whole crypto market gets, the harder it will be in the future for a single person to provide enough supply/demand to manipulate the price a lot. The control of the market will get distributed from a few very rich people to more not that rich ones. This process takes time.

Small investors are left scratching heads why the price dips even when all the good news are coming including the ETF?

It will keep that way and they can get you to sell it when finally you'll there is nothing that can bring the price up. If you have bought ETH for $600, you will most likely be discourrage when the price finally be at $50. You might think its impossible but it can happen if you don't sell them for now.

whales and traders who control the crypto market, but they cannot 100% control the market, because sometimes some external aspects can affect the crypto market.

john McAfee and some other crypto figures just do global predictions. they are not traders. they are only investors and motivators who support crypto world development.

Big money is controlling the price of encryption, and the reason why the price of encryption fluctuates so much is because of them, so we still need to be cautious about the price.
