For me it is better to save money than to invest , In investing you can lose your money there in any chance and you don't have a control to it if you just deposited your money and the withdrawal it self is not automatic the website is probably scam saving money or holding them is really good too. Save your profit and hold them till you need them.
I would say that it is going to be better if we are going to do both and with bitcoin investments by just simply holding it we can have our own investment with it.
That's why I prefer to do both, whether it is with bitcoin or real money. I want to do both because it is my attitude to save money always.
