Bitcoin’s Investment Thesis – Volatility And Market Manipulation

h3 Several reasons for BTC’s high volatility

Cryptocurrencies (including BTC) are a highly volatile asset class: daily price movements reaching high-single digit percentage levels are quite frequent and daily changes of +/- 10–20% are also not uncommon. The average monthly Bitcoin return in US dollars over the last five years is c 10%, while the standard deviation of monthly returns is c 25%. This may be due to a combination of several factors. First, it is worth pointing out that only c 20% of circulating BTC supply is being actively traded (see Glassnode or Chainalysis for details).

Moreover, liquidity is dispersed across multiple trading venues (centralised and decentralised exchanges as well as OTC markets). Second, unlike traditional trading venues there are no ‘circuit breakers’ on crypto exchanges. Third, volatility is elevated due to the high level of activity of speculative retail investors (given the early stages of institutional adoption) who often use excessive leverage. Finally, BTC is difficult to value, with no broadly accepted valuation method.

Having said that, we also note that BTC has historically been a good enhancer of the Sharpe ratio within a broader cross-asset portfolio. This is because there has been only moderate positive correlation between monthly BTC returns versus major equity indices, with Pearson’s coefficient over the last five years at c 0.27–0.29 (c 0.16–0.18 over 10 years), according to our calculations.

Moreover, BTC and gold have shown no meaningful correlation with each other. Together with BTC’s strong performance over a longer time horizon (despite c 80–90% de-ratings from previous peak during bear markets), this translates into a positive impact even for a small 1–5% allocation to BTC (see below).

Allocation to some of the major altcoins (eg Ethereum) had an even more positive impact on portfolios. Having said that, we acknowledge that even a small crypto allocation may push the overall volatility of the portfolio beyond levels acceptable to some investors and investment managers. However, this may be at least partially mitigated by periodic (eg quarterly) portfolio rebalancing, as discussed in detail by CoinShares’ research.
