Wences Casares, CEO of bitcoin wallet Xapo and member of PayPal’s board of directors has made a compelling forecast on bitcoin’s value over the next decade.

The bitcoin entrepreneur and executive was speaking at the Consensus 2017 conference in New York. Taking the stage at a dinner organized by bitcoin and blockchain advocacy group Coin Center, Casares’ speech was quite the hit.

While we did not attend and are unable to find a video of the talk, there are a few notable takeaways from scatterings of his speech reported online. Putting bitcoin under the spotlight, Casares opined that “the internet doesn’t have a currency and it desperately needs one”, pointing to the world’s most popular cryptocurrency.

“The biggest mistake [would] be to buy more bitcoin than you can afford to lose. The biggest mistake is [also] not to own any bitcoin,” he told the gathered audience.

“Put 1% of your net worth in Bitcoin and forget about it for 10 years” Casares added, baiting new investors to adopt the cryptocurrency.

His speech also included a prediction for the cryptocurrency, where one bitcoin would hit $1 million before the next ten years.

Whoa. PayPal guy & @xapo @wences : only buy the #bitcoin you can afford… and predicts it will hit $1 million in 5-10 yrs #consensus2017

Casares has long been a tech entrepreneur. As the founder of Argentina’s first internet service provider, he is also among the earliest evangelists of Bitcoin. He went on to launch a retail bank in Brazil before eventually launching bitcoin wallet Xapo. In early 2016, Casares joined PayPal’s board of directors, with the payments giant describing him as a “recognized next-generation payment and crypto-currency thought leader.”

Still, Casares’ claim is arguably among the most bullish predictions for bitcoin prices yet. Certainly more than early Snapchat investor Jeremy Liew and Blockchain CEO Peter Smith who predicted bitcoin prices to hit $500,000 by 2030.

It remains to be seen if either of these claims come true. One late 2016 prediction that has already proved right saw Danish investment bank Saxo predict bitcoin prices to rise by 165% (bitcoin was trading around $750 at the time), to leap beyond $2,000 in 2017. Bitcoin prices broke beyond $2,200 yesterday and are continuing to surge ahead at the time of publishing.
