There is no better option. It really depends on you and the risk you want and are able to take. If you have low revenue, well, maybe it's a better option to keep your savings at the bank even if it doesn't bring you any benefits.
Keeping in banks is safest way to us but we are getting very less interest for the amount we are depositing. Saving is always to hold the money because it will be helpful in the emergency needs. Most of the people failed to save money because they don't know how to manage the money.
