According to Russian media outlet Izvestia, economist Denis Astafiev warned that during periods of economic instability, investments in cryptocurrencies, derivatives, and ICOs face extremely high risks, and the prices of crypto assets could plummet significantly due to market fluctuations, regulatory risks, technical vulnerabilities, or declining interest. He recommends that investors strictly limit the allocation of such highly volatile assets to between 5% and 10% of their total investment portfolio to avoid irreversible losses in extreme market conditions.
