warned that Bitcoin (BTC) "could face downside pressure into the weekend".
The reported that Bitcoin rapidly dropped from $39,416 at 11am on June 17 to $37,754 this morning after Musk's critical message.
In a further update at 12.30pm on Friday, Coindesk said that "Bitcoin was trading around $37,900 at press time and is down about three per cent over the past 24-hours.
"A significant loss of momentum over the past few months suggests an extended period of drawdowns similar to the previous bear market in 2018."
Musk's comment was the latest in a series of remarks he has made about Bitcoin's use of fossil fuel being destructive.
He's made numerous backflips over Bitcoin - alternatively supporting the cryptocurrency, before doing a U-Turn and indicating he's not a fan.
Each tweet he posts about Bitcoin sends buyers - or sellers - into a frenzy, to the fury of those pushing the digital money.
Bitcoin Magazine then issued multiple tweets based on information from The Cambridge Centre For Alternative Finance.
It tweeted that the centre "estimates that 76% of all miners use renewable energies as part of their mix.
"CoinShares estimates that total share of renewables may even be as high as 73%."
Computers are needed for complex mathematical calculations to put a new Bitcoin into circulation online.
This process is also known as mining.
A lot of energy is needed for Bitcoin mining and some experts are concerned that vast amounts of fossil fuels are being used to create this energy.
Musk's latest tweet come days after he said that Tesla "will resume transactions" with the cryptocurrency.
But, his vow comes with a major proviso - clean energy usage by Bitcoin miners must be "confirmed", he warned.
He announced that Tesla would allow transactions in Bitcoin once 50 per cent of the crypto's mining is done with clean energy.

"[It's] impossible to do with 100 per cent accuracy due to the decentralised nature of the industry and the impossibility of surveying every single mining operation in the world.
"We will never really know for sure why Musk said and did what he did.
"What we can all take from this episode, however, is that... even a 'genius billionaire' can easily get sucked into false narratives and do a trillion dollars’ worth of damage."
