If you want to save money, invest in real estate. The price of homes tend to increase at the rate of inflation over long periods. In short periods you can even make a decent profit.
Other than that start investing... Forex or BTC if you want to trade actively. If not active, invest in some of these start up crypto businesses. Some of them are promising and easy to invest in. If they were regular start ups you would never have heard of them and probably wouldn't have access if you did. So take the opportunity to find some promising ICOs and other projects and take advantage.
Good luck
Real estate business can be a good idea actually, because as you said the prices of homes or lands increases with the time so if someone buys a place now and keeps it for one or two years he would earn some good profit out of it, so that can be a good way of investment as well.
