There’s a bitcoin bubble, says Alibaba executive chairman Jack Ma

There is a bubble in the world’s most popular cryptocurrency even as the underlying technology holds promise for safeguarding privacy and ensuring security, according to Alibaba Group Holding executive chairman Jack Ma Yun.
“There is no bubble for blockchain, but there's a bitcoin bubble,” Ma said in a forum during the second World Intelligence Congress held in Tianjin on Wednesday.
A bubble is an economic cycle characterised by the rapid escalation of asset prices followed by a contraction, according to Investopedia. It is created by a surge in asset prices unwarranted by the fundamentals of the asset and driven by exuberant market behaviour.
“Personally, I’m quite bullish about blockchain,” said Ma about the distributed ledger technology behind cryptocurrency bitcoin. “Alibaba has been conducting research on blockchain for several years.”
