The investment is the riskiest way, but it can generate more potential earning than saving. However, saving cryptocurrencies (or holding) is another profitable method, if you re holding the most promising coins, because their prices are expected to go up highly in the near future.
And you think that savings too is not risky? What if the bank where you have your money had challenges and then liquidate, what do you think that will happen to your money, so there is nothing that is not risky, if we keep considering the risky part of it, we may end up not doing anything at all.
Investment is very keen to human man, because this is the legacy that you will lay down for your children, it is the name that you build down for them, savings could be tampered with at any time, but investment would never be tampered with unless you don’t know how to manage it. Rather than keeping that money in the bank for too long, what happens to using it to buy fix assets like land which will even appreciate more than any amount you can get from banks.
