Bitcoin's value rose 12 percent on Monday to just under $40,000.

That happened after Tesla CEO Elon Musk tweeted that the automaker will accept the cryptocurrency again as a means of payment if its production becomes more sustainable.

Musk has a special relationship with bitcoin.

In February, he announced that Tesla would accept the digital currency as a means of payment, but backtracked in May.

A month ago, Musk tweeted that too many fossil fuels are used in the production of bitcoin and he suspended the plans.

The bitcoin price then fell from 54,000 dollars (almost 45,000 euros) to less than 50,000 dollars.

As a result, 360 billion dollars in market value was lost.

On Sunday, Musk tweeted that Tesla can accept the coin again if a certain condition is met: "From the moment that 50 percent clean energy is used in mining bitcoins, Tesla will accept the coin again."

That sounded like music to bitcoin investors' ears.

The price of the digital currency, which in the meantime had fallen to about $36,000, quickly rose to $39,600.

This price is still a long way from the record price of more than $ 60,000.

@Cointelegraph This is inaccurate.

Tesla only sold ~10% of holdings to confirm BTC could be liquidated easily without moving market.When there's confirmation of reasonable (~50%) clean energy usage by miners with positive future trend, Tesla will resume allowing Bitcoin transactions.

Musk has been a big proponent of crypto for years and sees a "bright future" for it, but regularly adjusts his ideas about the largest crypto currency, bitcoin.

This leads to criticism from politicians and experts worldwide.

They suspect the richest man in the world of market manipulation, because the price moves about the bitcoin after every tweet from Musk.

On Friday, the director of the Dutch Central Planning Bureau (CPB) wrote that the Netherlands should ban the trading of cryptocurrencies, because he believes a crash is inevitable.
