It depends, what is exactly what you are trying to achieve, precious metals more than anything are a store of value and while they can go up very rapidly this happens in a period of time that is too short and then they do not move for years or even decades, which is more or less what is happening now, so only invest in them once you are happy with your capital.

However if what you want is to increase your capital in a significant manner then you have no option but to invest in other assets, and what can be better than to invest in bitcoin before it goes up in value during the next months?
