What is the 30 day rule in crypto?

The “30‑day rule” in crypto usually refers to tax guidance that resembles the traditional wash‑sale rule for stocks. Some tax authorities consider it abusive if you sell a coin to realize a loss and buy it back shortly afterward while your economic position barely changes. In practice, interpretations differ widely between countries and even accountants. Because crypto regulation evolves quickly, investors should consult local tax professionals before relying on any simple rule.
