Bitcoin Interest Is Soaring

Big tech companies like Tesla, Twitter and maybe Amazon are interested in bitcoin and it could take off again after several weeks of laying low.

Bitcoin soared close to US$ 40,000 last 26 July after electric carmaker Tesla expressed fresh support for the world's most popular cryptocurrency. The 15 percent leap in Asian trade to a one-month high pegged the value at US$ 39,681, buoyed also by reports that US retail titan Amazon was mulling the use of crypto technology.

Bitcoin later eased back to US$ 38,880 in European deals. Analysts attribute this sudden jump to several developments.

The US investment group Ark Invest organized last week what it called "The B Word", an event aimed at promoting the virtual currency.

The group had Tesla founder Elon Musk and Jack Dorsey of Twitter reaffirm their interest in bitcoin.

Musk has been ambivalent about the digital currency, sometimes singing its praises, while also expressing concern about its environmental impact.

This time he said Tesla would likely start accepting bitcoin as payment, which helped rekindle a flame under it.

Bitcoin had shot up by 290 percent over a one-year period to an all-time high of almost US$ 65,000 in April, before falling back by about 40 percent.

"The bulls are back in town, and this time it seems like they are back with a vengeance," said Naeem Aslam, an analyst at AvaTrade.

The second development that caused a social media buzz was a posting by Amazon for a job related to digital currencies and blockchain strategy.

"Bitcoin is flying once again and it would appear the credit is going to Amazon, or more specifically a job posting at the company," remarked Craig Erlam, an analyst at the online brokerage Oanda.

"What that actually means is anyone's guess but what it does do is excite crypto enthusiasts and gets the rumor mill pumping," he added.

Erlam suggested that traders who needed to buy bitcoin to fulfill contracts coming due might also have played a role.

"It seems some significant short covering is taking place as bearish traders have seen the writing on the wall and rushed to the exits, after seeing what bitcoin can do when the bulls take control," said the analyst.
