If you invest all your money in bitcoin you tenure of security is not sure because bitcoin is not stable. In bitcoin there possibility your money invested will loss because of the fluctuation of price value or you gain more profit when the value of bitcoin increase. There is no guarantee in bitcoin once you invest of all your money because the unstable price of it. While, in Gold once you invest all of your money you have a guarantee profit because the value of it is stable and never fluctuate instead the price of it is increasing as long as the time years are running.
I think it is okay to take some risk to get more profit, I hope if we invest on bitcoin our investment will be returned to us many times on our investment, but if we invest in gold the profit may be in one or 2 times on the investment, If you ask me I will always say bitcoin is the best investment.
