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.
because saving for a long time mean you are decreasing the value of you money due to inflation, whereas with investment money will grow so I will always prefer you investment, and specially investment in bitcoin is more profitable and is also a safe saving.
