'He put his heart and soul into the company, in every stage of its growth. He led by example with his intellect, generosity, humility, diligence and creativity,' the company said in a statement. 

'TT was a respected thought leader and widely recognised as a pioneer for the industry. His depth of knowledge, his willingness to collaborate and his desire to always help others benefited countless start-ups and individuals,' the firm added.

The statement did not say where Kullander passed away.

Amber Group is based in Singapore and its website says it has a 'presence in Athens, Geneva, Dubai, Hong Kong, Istanbul, London, Mexico City, Taipei, Tokyo, Vancouver, and Zurich'. 

In a tribute posted to Twitter, Annabelle Huang, a managing partner at Amber Group, said: 'Lost a dear friend who has changed my life, among many others, in ways he didn’t realize.'

She said Kullander was 'the best of us - a rare mix of both a scholar and a degen - always generous with his time, uncompromisingly honest, and a fierce voice in our industry. His legacy will live on.'

Kullander, a former Morgan Stanley and Goldman Sachs trader, founded the Amber Group in 2017. The company was valued at $3billion (£2.4billion) in recent months.

Amber Group said earlier this month that it was an 'active trading participant' on the collapsed firm FTX.

Kullander's death comes just weeks after another young cryptocurrency millionaire died.

Nikolai Mushegian, 29, drowned on a Puerto Rico beach after tweeting that he feared the CIA and Mossad were going to murder him.

Mushegian had a history of mental health problems and his family do not believe there was any foul play. 

In a tweet hours before he died, he said: 'CIA and Mossad and pedo elite are running some kind of sex trafficking entrapment blackmail ring out of Puerto Rico and Caribbean islands.

'They are going to frame me with a laptop planted by my ex [girlfriend] who was a spy. They will torture me to death.' 

However, some in the cryptocurrency community in Puerto Rico are suspicious of the timing of his death.

He was discovered by a surfer in the water at Ashford Beach on October 29, fully clothed and carrying his wallet.
