Yes. Bitcoin and other cryptocurrencies are extremely risky investments as you'll never know what their price would be in a couple of years from now. Their volatility brings a certain level of uncertainty, which makes them quite troublesome for preserving your investments in the future. As such, the key here would be to diversify our investments to protect ourselves from the risks associated with cryptocurrencies.
Cryptocurrencies like Bitcoin not only bring investment opportunities but can also serve as a form of savings that would give you greater rates per year than storing your money in a bank account.
