Bitcoin's significant growth days are behind it, and a dramatic collapse of the cryptocurrency could trigger widespread economic damage, according to Simeon Willis, chief investment officer at consultancy XPS.

Willis stated that while Bitcoin has yielded substantial returns for some investors in the past, its performance has lagged behind other assets in recent years. He characterized Bitcoin as a 'one trick pony' because its underlying blockchain technology is not easily adaptable to other rapidly evolving areas of digital finance. The cryptocurrency's future hinges on its adoption as a functional currency, and without it, Willis warned, it could "wither fast."

Despite not endorsing Bitcoin's investment case, Willis expressed concern about the potential fallout from its failure. He noted that the evaporation of a market valued at approximately £1 trillion could lead investors to divest from riskier assets like equities and seek refuge in safer options such as bonds. Such a shift, coupled with direct and indirect wealth losses, would likely reduce consumer spending and negatively impact economic growth.

Historically, Bitcoin has experienced significant volatility. In October, it reached an all-time high of $126,000, only to fall below $60,000 by July. A rally to over $80,000 was fueled by a U.S. Treasury intervention in bond markets and anticipation of favorable U.S. legislation, though recent days have seen a downturn amid ongoing bond market volatility.

Willis highlighted that the exceptional pre-2021 growth, where Bitcoin returned 7,000 percent between 2016 and 2021, is not indicative of its current trajectory. In the last five years, it has returned only 72 percent, with over a third of that growth occurring in the past month. This performance trails behind traditional investments like the FTSE All World global equity index, which has delivered 75 percent over the same period.

He pointed out that blockchain technology, the core of digital finance, does not inherently require cryptocurrency. For instance, the planned digital UK government bond, DIGIT, set for issuance in 2027, will utilize HSBC Orion, a Sterling-based blockchain that does not involve cryptocurrency. Furthermore, Bitcoin's blockchain is limited to facilitating Bitcoin transactions and lacks the smart contract capabilities and programmability of other blockchains, which could potentially eclipse Bitcoin with superior features.

Willis cautioned that a rapid failure of Bitcoin is plausible, drawing a parallel to the swift collapse of Silicon Valley Bank. He also noted that stablecoins, like USD Tether which holds approximately $140 billion in coins, could be affected. While three-quarters of Tether's backing assets are considered low-risk, the remaining quarter includes more volatile assets such as precious metals and Bitcoin itself.

The potential consequences of a Bitcoin failure extend to the broader digital asset market. A sharp withdrawal from digital markets could impact other cryptocurrencies and stablecoins. A significant loss of value in the cryptocurrency market could trigger a sell-off in equity markets, reminiscent of the 1998 fallout from the LTCM hedge fund failure and Russian debt default. Such events typically lead to a double-digit decline in equity markets.

Ultimately, a disorderly collapse of Bitcoin could hinder the development of the digital asset market, which promises reduced transaction costs, faster settlement times, and new investment opportunities for individuals, potentially democratizing access to high-return private markets previously dominated by institutional investors.
