A Reddit user who claimed in a post a month ago to be a Tesla Inc insider and knew about the electric car maker's purchase of bitcoin said on Tuesday that his assertions were not true.

The user's original post here stating Tesla was buying bitcoin drew little attention when it appeared Jan. 2. But it received a second look Wednesday, a day after the electric carmaker and its CEO Elon Musk disclosed a $1.5 billion investment in the cryptocurrency that sent bitcoin to fresh highs.

Reuters could not independently verify the user's identity or whether his initial or subsequent claims were accurate.

Tesla did not respond to an email to its press office.

"I am a software dev working at R&D at Tesla in California, over the past 72 hours our company bought 24701 BTC at an average price of 33142$," the user with the handle TSLAinsider posted on Reddit last month.

"I have no idea what will happen once this reaches the newspapers but I think the price will explode even more," the user wrote.

"I told you so," TSLAinsider wrote on Monday after the Tesla news on bitcoin. "I got laughed at and downvoted."

The user told the New York Post late on Tuesday that he is in fact a prankster from Germany.

"If you want to know the truth: I am a young German guy and I was on Acid while I did this post in the last month," the Post quoted him as saying. "I had this afflatus that Elon is going to buy Bitcoin, so I created this trollpost."

The user, who told the Post his name was Hendrik, told Reuters that the information in the New York Post article was correct.

Tesla said it started purchasing bitcoin in January. The New York Post added that with the timeline on the Reddit post, Tesla would have had to start buying bitcoin in late December.
