All of your option to invest I would like make investment at crypto, maybe crypto have different way to increase our money than other investment kind. Look at how your money growing more if you invest at bitcoin and compare how your money could growing slow by investment at gold.
It is true that investing in bitcoin provides big profits in the short term, for example the price of bitcoin in December 2017 soared. The problem is whether the high prices will come back again? Then the fluctuations are too fast, so it's easy to panic. So, I don't dare to invest too much bitcoin. Real Estate is a long-term investment choice. The problem is if we need money, it's not as fast as selling a car. But it is mandatory because real estate includes a safe investment. For me, in the short and long term, gold investment is the most preferred, because gold prices always rise. When we need money, to sell it quickly and easily.
