It comes as Bitcoin soars to record sums, currently valued at £23,000 ($32,000) per coin.
And Bitcoin reached a record high of $41,973 on January 8 this year.
In December 2018, a single coin was worth $3,300, and in November 2013, one coin was worth as little as $350.
This phenomenal rise has made multimillionaires and billionaires of some investors.
Now experts have told The Telegraph how there are fears that Bitcoin “whales” hold too much sway over the market.
“The Bitcoin trading market is very thin,” crypto-sceptic David Gerard said, speaking to The Telegraph.
“There is not a lot of available volume to trade.
“The big players can easily move the price.
“And there are all kinds of trading shenanigans, which would not happen on a regulated market.”
It’s believed that around 2,500 “whales” control roughly 40% of the Bitcoin market.
Experts worry that single trades can make huge changes to the price of Bitcoin – swamping any movements by smaller investors.
Gerard, who wrote Attack of the 50 Foot Blockchain, added: “These big players have lots of Bitcoin and are very active in the market. Any one of them could crash it.”
Some trades can have staggering values.
It’s common to see dozens of single trades each worth tens of millions in a single day.
And Bitcoin’s price is highly volatile, having dropped by around $10,000 from its high of $42,000 earlier this month.
However, Bitcoin supporters argue that the coin has long-term value – evidenced by its enormous rise over the past decade.
What is Bitcoin?
- Bitcoin is a virtual currency
- It’s traded between people without the help of a bank
- Every transaction is recorded in a public ledger, or “blockchain”
- Bitcoin is created by mining
- Mining involves solving difficult maths problems using computer processors
- Bitcoin can be traded anonymously, which can make it a popular way of funding illegal activities
- The value of Bitcoin fluctuates wildly
- Bitcoin is one of many different cryptocurrencies, but by far the most popular
Regardless of its price, Bitcoin continues to be a wild cultural phenomenon.
The internet went into a frenzy when a computer programmer recently revealed that he has just two password guesses left to access a £180million Bitcoin account.
The device allows for ten attempts — and he’s tried eight times.
If he doesn’t get it right in the next two tries, it will be permanently encrypted and the fortune lost forever.
German-born Stefan was given the Bitcoin in 2011 as a reward for making an animation.
But the price of Bitcoin has since soared — with a rise of 720 per cent since March 2020 alone.
Speaking about his lockout Stefan, who now lives in San Francisco in the US, said: “I would just lay in bed and think about it.
“Then I’d go to the computer with some new strategy and it wouldn’t work and I’d be desperate again.”
Many others have struggled to cash in on cryptocurrencies as they have also forgotten their passwords.
Wallet Recovery Services, which helps find lost digital keys, said it gets 70 requests a day.
Of course, £180million is a small sum when it comes to Bitcoin.
The richest Bitcoin wallet currently holds 141,452 Bitcoin – the equivalent of $4.6billion.
