Investment bank UBS thinks bitcoin is neither money nor a viable asset class - not yet at least.

The Switzerland-based company's assessment was featured in a research report on the world's largest crypto by market capitalization, which was circulated to clients and released on Thursday.

Published by UBS strategists, the report concludes that bitcoin "falls short of criteria that need to be satisfied to be considered money." It explains,

However, the authors don't rule out the possibility that bitcoin could one day become these things.

They argue that if bitcoin can achieve scalability and regulatory support, it could one day become "a viable payment mechanism and/or a legitimate asset class in which even the most conservative and traditional investors can participate."

Likewise, they note their plans to "keep on top of these developments," as "many" see promise in cryptocurrency's underlying blockchain technology.

According to the report, the research was the banking giant's answer to its investors, who are becoming increasingly interested in the cryptocurrency space.

"We have received many questions on the subject, which we hope to address in this educational piece," the authors wrote in the publication.

The authors' findings were based on comparisons of bitcoin with "macro variables and its performance against various asset classes." They frequently draw parallels between bitcoin and online payments provider PayPal, and conclude that bitcoin "diffusion" could follow trends in online payments.

This is not the first time UBS has expressed a cautious view on cryptocurrency. In 2017, it declared cryptocurrencies a "speculative bubble" in a report due to sharp rises in price at the time. Nonetheless, the bank has consistently been bullish on blockchain, and advised investors in the same report that "blockchain is likely to have a significant impact" on a variety of industries.
