The only investment that is now allowing to make money, atleast looks like, are the casinos bankroll, others ways usually lead us into scam projecs in the short- medium period. Sometimes savings is the best way, even not getting nothing extra for those, you are able to get interest at your bitcoins due the volatility.
I agree that sometimes savings is the best way because I am thinking that a good saver will be always a good investor. Because while he is saving money he gives value to it and he will spend it wisely whether it is for investment or not. And for me, to have a good investment you need to have good savings for backing it up.
Savings is just a first step to success, no one will be rich if a person does not know how to save. It starts from the beginning since when you are successful in savings, you can gain experience on that and would make you a discipline person.
