Bitcoin extended gains on Tuesday to a record high as the afterglow of Tesla Inc’s investment in the cryptocurrency had investors reckoning it would become a mainstream asset class for both corporates and money managers.

Bitcoin has more than doubled over two months as institutional investors search for alternative wealth stores and retail traders ride the wave. Monday’s leap after Tesla’s announcement was its largest daily rise in more than three years.

It climbed to a new peak of $48,216 late in the Asian afternoon on Tuesday. Rival cryptocurrency ethereum had struck a record high of $1,784.85 in the early morning.

Shares of companies that provide trading platforms for bitcoin and the technology to “mine” the cryptocurrency surged in China, South Korea, and Australia, and big computer chip making companies such as SK Hynix also rose.

The U.S. dollar slumped against most currencies.

Analysts figuredTesla’s announcement that it had bought $1.5 billion in bitcoin and that it would take the cryptocurrency as payment for cars is part of a larger shift as companies and big investment houses follow small traders into the asset.

“While you can now buy a Tesla with bitcoin, I wouldn’t suggest doing so,” said Michael Bucella, partner at crypto investment firm BlockTower on CNBC. “We’re in a position where these are the earliest phases of an allocation to bitcoin from the institutional and corporate community.”

Bitcoin is already up 62% this year, on top of a 300% rally last year, as investors search for alternatives to the greenback because of the U.S. Federal Reserve’s 0% interest rates.

Central bankers and regulators, particularly in China, are also starting to embrace issuing their own digital currencies for everyday use, in a major break from the conventional workings of global finance.

“Digital currencies, it seems clear to us, are going to be an increasing part of financial architecture very broadly and potentially portfolios moving forward,” Ben Powell, APAC chief investment strategist at BlackRock’s Investment Institute, said on CNBC.

“There isn’t just news in the U.S. with the bitcoin situation, but in China we’ve got a rollout of China’s digital currency with so-called ‘red packets’.”

Tesla boss Elon Musk has long been a cryptocurrency fan - he has talked them up online - but Tesla’s hard currency investment came as a surprise that has put a rocket under the sector.
