Max Levchin, co-founder of PayPal, has revealed that he is a big fan of blockchain technology, but is still making up his mind on bitcoin.
However, on the cryptocurrency, he said:
It's yet to be seen whether bitcoin is a currency "or just a way to make money fast," he added.
Levchin's stance on bitcoin is notably different that of fellow PayPal co-founder Peter Thiel, who told CNBC in October that he believes bitcoin has a promising future, though he was skeptical of most other cryptocurrencies.
"It's like a reserve form of money, it's like gold, and it's just a store of value. You don't need to use it to make payments," he said at the time.
Those who are criticizing the cryptocurrency are "underestimating" it, Thiel argued.
