Crypto vs Stock Market Comparator 2026

The comparison between crypto and stocks is one of the most frequent among retail investors. Bitcoin has displayed a spectacular average annualised return since its creation, but with extreme volatility: drawdowns of 50 to 80% are not uncommon during bear cycles. In contrast, a diversified index like the MSCI World or S&P 500 offers a historical average return of 7 to 10% per year with much lower volatility.

Taxation also differs. In France, crypto capital gains are subject to the 30% flat tax (PFU) upon conversion to euros. In the stock market, via a PEA held for more than 5 years, only the 17.2% social contributions apply, representing a significant tax advantage. This parameter is often overlooked in raw performance comparisons, but it can represent several thousand euros of difference over the long term.

Most wealth management advisors recommend combining both asset classes in a diversified portfolio: a solid base in equities (via PEA and ETFs) representing 80 to 90% of the portfolio, and a satellite exposure of 5 to 10% in crypto to capture upside potential while limiting overall loss risk. The key is to adapt the allocation to your risk tolerance and investment horizon.
