Saving money in a savings account is like putting money in a pocket with holes. Banks only give you interests that are lower than the inflation rate. Its how they make money. You are better off investing in ventures (Crypto currency) that give a return higher than the inflation rate.
this is true, banks gives 0.5% to savings account, but it should be noted that banks shouldnt be seen as an investment, its a means of saving money for later days, but it is better to invest in crypto with high returns than to save ones money in a savings account with little or no interest rate. But in all, one should trade cautiously.
