only keep in mind trading and arbitrage having even higher risk than buying property which is quite best option so far and will not going to make you lose your money,you can use the property and can sell it whenever you want
A property is a good investment if you have the means to buy it. If you have a property,and you are living in it os ok.If you have a property and rent it out,its a best investment as you have a rental income at the same time. But if you have a property and you let it idle and wait for the price to go up, its not maximized.
