Yeah saving it on the bank will gain you but it's very low, it's like you save $1,000 there and you'll earn $1 or $10 if I'm right. But it's good to save some money in the bank because that will tell you on how wealthy you are and that is something needed by everyone of us. And if your focus is earning at this moment, then go invest.
exactly. actually saving will only make your money save and stored. but it will not increase your money. no matter if you save in money and get interests. (interest is very low) and investment will increase your money (it can decrease too if you loose) now it is upto you what would you choose.
