One reason an investor might consider bitcoin for their portfolio is precisely its volatility: bitcoin is not subject to the wash sale rule as long as it's not regulated like a security, so investors can sell into a loss for the tax benefit of offsetting their capital gains elsewhere, and repurchase immediately, avoiding the usual constraint of having to wait 30 days before repurchasing in order to claim the tax benefit of the realized loss. In this context, the price swings provide ample opportunity for tax optimization.
