Yes. Because banks pay very low interest rates in savings accounts, you're better off looking for investment opportunities that will greatly expand your capital in the long term. Of course, as with any investment there is a risk, but the higher the risk, the higher the reward will be.
I think that it is best this way, as it gives you a huge opportunity to build your wealth within a short time frame. This is especially in the field of cryptocurrencies, as there are many in the market which pay high rates to their stakeholders. If you manage to take advantage of this, then you'll be able to make much more money than just saving it in a bank.
Nevertheless, if you take the time and effort to analyze the price movements of cryptocurrencies, and devise strategies to minimize your losses, then you'll do fine towards building your wealth that will last for many years to come. Just my thoughts
