where should i invest and why ?

Gold has gain a lot starting of this year. It is due to the potential rate hike by Fed. So a lot of people are shifting their money away from stock and into gold. This is normally the trend. And as you have known, the fed did not raise the rate in the june, so people are starting to be interested in stock again so money start to shift back into stock and that partially account for the recent drop in gold. However, we cannot use the drop in gold to say that gold is not a good investment. Anything that goes up will go down too. To me, gold is always a good safe investment while bitcoin is a good and risky investment. You can profit a lot from bitcoin but you also can lose a lot. While gold is a slow and growing investment.

Lol and I think that is a smart decision to make as gold will surely give you good profits if you hold it for 10 years as we don't know whether bitcoin will survive for next 10 years or not so holding it can be risky.
